From 1f855f23fc94abedd56ca83c058d19691e7addec Mon Sep 17 00:00:00 2001 From: Jeff Anderson Date: Tue, 26 Jul 2022 15:44:24 -0600 Subject: [PATCH 001/244] Created module to do distribution computations for quantile filters. Use calls from this to do state space transforms in filter_assim. Also doing initial conversion for observations priors. Not yet doing the computation of probit space increments for observed variables. This reproduces (bitwise!) the out of the repo L96 test. However, it should not be assumed that the code is correct since the normal transforms being done so far are equivalent to nops and things might be working for bad reasons. --- .../modules/assimilation/assim_tools_mod.f90 | 183 +++++-------- .../quantile_distributions_mod.f90 | 245 ++++++++++++++++++ 2 files changed, 303 insertions(+), 125 deletions(-) create mode 100644 assimilation_code/modules/assimilation/quantile_distributions_mod.f90 diff --git a/assimilation_code/modules/assimilation/assim_tools_mod.f90 b/assimilation_code/modules/assimilation/assim_tools_mod.f90 index 33e41668a4..f59a503cd1 100644 --- a/assimilation_code/modules/assimilation/assim_tools_mod.f90 +++ b/assimilation_code/modules/assimilation/assim_tools_mod.f90 @@ -71,6 +71,10 @@ module assim_tools_mod use quality_control_mod, only : good_dart_qc, DARTQC_FAILED_VERT_CONVERT +use quantile_distributions_mod, only : dist_param_type, convert_to_probit, convert_from_probit, & + convert_all_to_probit, convert_all_from_probit, & + norm_cdf, norm_inv, weighted_norm_inv + implicit none private @@ -370,6 +374,10 @@ subroutine filter_assim(ens_handle, obs_ens_handle, obs_seq, keys, & logical :: local_ss_inflate logical :: local_obs_inflate +!

A matlab script +QCEFF_summary_results.m in this directory was run to create two files with the best case +localization parameters for each ensemble size: +QCEFF_SUMMARY_PRIOR adn QCEFF_SUMMARY_POST +The first of these has the results for the inflation cases with the smallest prior RMSE, while the +second has the results for the inflation case with the smallest posterior RMSE.

These runs can be compared +to similar REV results in the DART_EXPLORATION branch/directory. The tuning was done with the script +rev_state_space_auto_filter.csh. The results are in REV_QCEF_RESULTS. The script +REV_QCEFF_summary_results.csh extracted the best cases and wrote them to +REV_QCEFF_SUMMARY_POST and REV_QCEFF_SUMMARY_PRIOR. The 10 different runs were created +using rev_summary_runs.csh and written to REV_QCEF_output_ten. These are the results that are +used for the figure results for the QCEF paper part 2. + +Note that there are a handful of cases that fail when generating the ten cases.

In the long-term, need to worry about what happens if sd is very small as opposed to formally zero. --- .../quantile_distributions_mod.f90 | 46 +++++++++++++++---- 1 file changed, 37 insertions(+), 9 deletions(-) diff --git a/assimilation_code/modules/assimilation/quantile_distributions_mod.f90 b/assimilation_code/modules/assimilation/quantile_distributions_mod.f90 index 2cfd9cf676..df3834c307 100644 --- a/assimilation_code/modules/assimilation/quantile_distributions_mod.f90 +++ b/assimilation_code/modules/assimilation/quantile_distributions_mod.f90 @@ -172,8 +172,16 @@ subroutine to_probit_bounded_normal_rh(ens_size, state_ens, p, probit_ens, & if(use_input_p) then !

Added a beta_distribution module that was developed by Chris Riedel. Added in testing code to the gamma, beta and normal distributions modules and made the algorithms more efficient. Added a higher accuracy inverse cdf for the normal module but it is switched off for now. It is much more expensive in return for improved accuracy. --- .../assimilation/beta_distribution_mod.f90 | 206 +++++++++--------- .../assimilation/gamma_distribution_mod.f90 | 78 ++++--- .../assimilation/normal_distribution_mod.f90 | 186 +++++++++++++--- .../quantile_distributions_mod.f90 | 82 +++++-- .../perfect_model_obs/perfect_model_obs.f90 | 4 - 5 files changed, 383 insertions(+), 173 deletions(-) diff --git a/assimilation_code/modules/assimilation/beta_distribution_mod.f90 b/assimilation_code/modules/assimilation/beta_distribution_mod.f90 index 6df99f25bb..07d53dcf68 100644 --- a/assimilation_code/modules/assimilation/beta_distribution_mod.f90 +++ b/assimilation_code/modules/assimilation/beta_distribution_mod.f90 @@ -6,9 +6,9 @@ module beta_distribution_mod -use types_mod, only : r8, PI +use types_mod, only : r8, PI -use utilities_mod, only : E_ERR, error_handler +use utilities_mod, only : E_ERR, error_handler use random_seq_mod, only : random_seq_type, random_uniform @@ -17,44 +17,66 @@ module beta_distribution_mod public :: beta_pdf, beta_cdf, inv_beta_cdf, random_beta, test_beta -character(len=512) :: errstring +character(len=512) :: errstring character(len=*), parameter :: source = 'beta_distribution_mod.f90' +real(r8), parameter :: failed_value = -99.9_r8 + contains !----------------------------------------------------------------------- subroutine test_beta +!

Ensmble sizes of 20, 40, 80 and +160 were used. An initial tuning exercise was done by running a case for each of 8 localization +halfwidths. The results of these tuning cases are in QCEF_RESULTS. The runs were created by the +script state_space_auto_filter.csh which is found in each directory. A matlab script +QCEFF_summary_results.m in this directory was run to create two files with the best case +localization parameters for each ensemble size: +QCEFF_SUMMARY_PRIOR adn QCEFF_SUMMARY_POST +The first of these has the results for the inflation cases with the smallest prior RMSE, while the +second has the results for the inflation case with the smallest posterior RMSE. The second +files were not used further here. + +A set of 10 runs from different initial conditions was performed for each of the ensemble sizes +with the optimal localization setting. This was done using the script summary_runs.csh in this +directory and generates output in the file QCEF_output_ten. + +The nameslist for these runs comes from INPUT.NML.QCEF.TEMPLATE. The only thing of interest is +the inflation settings which had inf_lower_bound = 0 and inf_upper_bound = 1000000. The inf_damping +was 0.9. The inf_sd_initial and inf_sd_lower_bound were set to 0.6 for the NONID and SQRT cases +but to 0.2 for the SQUARE and CUBE cases to try to stabilize the inflation. + + +This entire process was repated for the NONID, SQRT and SQUARE cases with the inflation lower bound +set to 1 (no deflation) and the upper bound set to 2. The damping was 0.9 and the +inf_sd_initial and inf_sd_lower_bound were the standard 0.6. The input.nml came from +REV.INPUT.NML.QCEF.TEMPLATE. These runs can be compared +to similar REV results in the DART_EXPLORATION branch/directory. The tuning was done with the script +rev_state_space_auto_filter.csh. The results are in REV_QCEF_RESULTS. The script +REV_QCEFF_summary_results.csh extracted the best cases and wrote them to +REV_QCEFF_SUMMARY_POST and REV_QCEFF_SUMMARY_PRIOR. The 10 different runs were created +using rev_summary_runs.csh and written to REV_QCEF_output_ten. These are the results that are +used for the figure results for the QCEF paper part 2. + +Note that there are a handful of cases that fail when generating the ten cases. This is noted +by the number of steps in the output files (should be 5500 for success). Failures only occured +for the SQUARE forward operator. + +Note 2: One of the cases in the output_ten files for each ensemble size should be idential to +the tuning run. However, in some cases the tuning runs were done for the first on the ten +perfect_ics file, and in some for the tenth. This should not impact the validity of the result +in any way but could be confusing when trying to understand how the cases were generated. + +Several plotting scripts are available here. +plot_ten_nonid_rmse.m, plot_ten_sqrt_rmse.m, and plot_ten_square_rmse.m for the different cases. +These also access comparable results from the DART_EXPLORATION directory (EAKF, EnKF, RHF +with standard regression). From 595111aa17093f872352d07a2c7998fa4ac8c65a Mon Sep 17 00:00:00 2001 From: Jeff Anderson Date: Sat, 28 Jan 2023 17:29:08 -0700 Subject: [PATCH 060/244] A number of independent changes 1. Added namelist control for two parameters, whether to do a logit or probit transform and whether to fix cases where the incoming ensemble members exceed the bounds. 2. Added code to do to_probit and from_probit test every time to_probit_bounded_normal_rh is called. Want these to be very nearly inverses. 3. Corrected imprecise computations of quantiles in to_probit_bounded_normal_rh for the case of a previously computed distribution when in normal tails. 4. Corrected a bug in ens_quantiles that assigned improper quantiles when ensemble members were exactly at the upper bound. Unfortunately, active debugging is continuing in this commit so there are a bunch of nasty writes. Bottom line: This code works while maintaining pretty small inversion differences for the tracer test case with a positive tracer when assimilating both kinds of obs. It does not maintain small differences for the case with a negative tracer or for a case with tracer bounded above at 1. This needs to be fixed. --- .../quantile_distributions_mod.f90 | 181 +++++++++++++++--- 1 file changed, 150 insertions(+), 31 deletions(-) diff --git a/assimilation_code/modules/assimilation/quantile_distributions_mod.f90 b/assimilation_code/modules/assimilation/quantile_distributions_mod.f90 index 3efb8c1c86..9861ea2622 100644 --- a/assimilation_code/modules/assimilation/quantile_distributions_mod.f90 +++ b/assimilation_code/modules/assimilation/quantile_distributions_mod.f90 @@ -11,7 +11,8 @@ module quantile_distributions_mod use sort_mod, only : sort, index_sort -use utilities_mod, only : E_ERR, error_handler +use utilities_mod, only : E_ERR, error_handler, do_nml_file, do_nml_term, nmlfileunit, & + find_namelist_in_file, check_namelist_read use algorithm_info_mod, only : probit_dist_info, NORMAL_PRIOR, BOUNDED_NORMAL_RH_PRIOR, & GAMMA_PRIOR, BETA_PRIOR, LOG_NORMAL_PRIOR, UNIFORM_PRIOR @@ -28,7 +29,7 @@ module quantile_distributions_mod public :: convert_to_probit, convert_from_probit, convert_all_to_probit, & - convert_all_from_probit, dist_param_type + convert_all_from_probit, dist_param_type, ens_quantiles type dist_param_type integer :: prior_distribution_type @@ -41,8 +42,16 @@ module quantile_distributions_mod character(len=512) :: errstring character(len=*), parameter :: source = 'quantile_distributions_mod.f90' +!

Added a check to the truncated_normal_like to deal with the possibility of a zero observational error variance. Added temporary null likelihood test of the rhf increments to make sure that the distribution there is stable; it kills execution if violated. Modified the threshold computation for the RH transformation to allow the possibility of roundoff error. Changed the name of the namelist parameter that controls fixing of bounds violations to note that it is only applied to the bounded_normal_rh. Added a function to do bounds fixing when the namelist is true. Added bounds correction to both parts of the to_probit_bounded_rh subroutine. All tests, all cases, all ensemble sizes work for the L96 tracer with these settings. --- .../modules/assimilation/assim_tools_mod.f90 | 29 +++++++- .../quantile_distributions_mod.f90 | 73 +++++++++++++++---- .../lorenz_96_tracer_advection/work/input.nml | 2 +- 3 files changed, 85 insertions(+), 19 deletions(-) diff --git a/assimilation_code/modules/assimilation/assim_tools_mod.f90 b/assimilation_code/modules/assimilation/assim_tools_mod.f90 index 248762fe97..bac51c335b 100644 --- a/assimilation_code/modules/assimilation/assim_tools_mod.f90 +++ b/assimilation_code/modules/assimilation/assim_tools_mod.f90 @@ -926,6 +926,8 @@ subroutine obs_increment(ens_in, ens_size, obs, obs_var, obs_kind, obs_inc, & logical :: bounded(2) real(r8) :: bounds(2), like_sum +real(r8) :: t_likelihood(ens_size), obs_inc_temp(ens_size) + !

Removed code that is no longer used from assim_tools_mod and quantile_distributions_mod. Key change was modifying inf_rh_cdf so that it can use a discrete likelihood and do Bayes, or work with an uninformative likelihood if none is passed via an optional argument. These modifications lead to a change of answer for some, but not all, of the idealized tracer test cases. With the new 1e-10 threshold for observation space test inversion, this code runs for all cases with no errors and does not require fix_bound_violations to be true. --- .../modules/assimilation/assim_tools_mod.f90 | 302 ++---------------- .../assimilation/normal_distribution_mod.f90 | 4 +- .../quantile_distributions_mod.f90 | 19 +- .../assimilation/rh_distribution_mod.f90 | 203 +++++++----- 4 files changed, 164 insertions(+), 364 deletions(-) diff --git a/assimilation_code/modules/assimilation/assim_tools_mod.f90 b/assimilation_code/modules/assimilation/assim_tools_mod.f90 index bac51c335b..cdf4468091 100644 --- a/assimilation_code/modules/assimilation/assim_tools_mod.f90 +++ b/assimilation_code/modules/assimilation/assim_tools_mod.f90 @@ -80,6 +80,8 @@ module assim_tools_mod use gamma_distribution_mod, only : gamma_cdf, inv_gamma_cdf, gamma_shape_scale, & gamma_gamma_prod + +use rh_distribution_mod, only : inv_rh_cdf, rh_cdf_init implicit none @@ -1058,9 +1060,9 @@ subroutine obs_increment(ens_in, ens_size, obs, obs_var, obs_kind, obs_inc, & t_likelihood = t_likelihood / sum(t_likelihood) call obs_increment_bounded_norm_rhf(ens, t_likelihood, ens_size, prior_var, & obs_inc_temp, bounded, bounds) - if(maxval(abs(obs_inc_temp)) > 1e-11_r8) then - call error_handler(E_ERR,'obs_increment', & - 'Null increment tests exceed the threshold', source) + if(maxval(abs(obs_inc_temp)) > 1e-10_r8) then + write(msgstring, *) 'Null increment tests exceed the threshold ', maxval(abs(obs_inc_temp)) + call error_handler(E_ERR, 'obs_increment', msgstring, source) endif !-------------------------------------------------------------------------- @@ -1228,14 +1230,12 @@ subroutine obs_increment_bounded_norm_rhf(ens, ens_like, ens_size, prior_var, & ! is_bounded indicates if a bound exists on left/right and the ! bound value says what the bound is if is_bounded is true -!

This includes a new more comprehensive test of F-1(F(x)) inversion accuracy. The new algorithm uses a first guess from the old approximate method that greatly reduces the number of iterations, new numerical derivative computations, and an improved convergence criterion. Also commented out the inversion tests for the RHF in obs space and changed constants for other inversion test succes. Modified assim_tools so that probit transforms are NOT done for observations that have failed forward operators. An algorithm_info_mod.f90 that is cam-fv specific is committed in the cam-fv/work directory. The cam-fv input.nml is updated to work with the probit transforms. --- .../modules/assimilation/assim_tools_mod.f90 | 34 +-- .../assimilation/normal_distribution_mod.f90 | 68 +++--- .../quantile_distributions_mod.f90 | 6 +- .../assimilation/rh_distribution_mod.f90 | 18 +- models/cam-fv/work/algorithm_info_mod.f90 | 207 ++++++++++++++++++ models/cam-fv/work/input.nml | 56 +++-- 6 files changed, 314 insertions(+), 75 deletions(-) create mode 100644 models/cam-fv/work/algorithm_info_mod.f90 diff --git a/assimilation_code/modules/assimilation/assim_tools_mod.f90 b/assimilation_code/modules/assimilation/assim_tools_mod.f90 index cdf4468091..3d5566be2e 100644 --- a/assimilation_code/modules/assimilation/assim_tools_mod.f90 +++ b/assimilation_code/modules/assimilation/assim_tools_mod.f90 @@ -554,13 +554,17 @@ subroutine filter_assim(ens_handle, obs_ens_handle, obs_seq, keys, & !

Incorporated names changes from normal_distribution_mod Added gamma_mn_var_to_shape_scale subroutine Revised gamma_shape_scale to use gamma_mv_var_to_shape_scale normal_distribution_mod.f90 Changed names of all public routines to be consistent with the usage in other distribution mods and to use the full 'normal' instead of 'norm' Added routines normal_mean_variance and normal_mean_sd bnrh_distribution_mod.f90 Changed name from rh_distribution_mod Changed all external interfaces to use bnrh_ consistent with other distribution modules Moved the cached dist_for_unit_sd to module storage with saved_ens_size Removed use of dimension 2 bounds arrays Carefully distinguished sorted from unsorted state and quantile arrays Modified inputs to bnrh_cdf_initialized_vector to allow the incoming sorted array for the bnrh, and the points at which to evaluated that to have different sizes. Removed extraneous tail_amplitudes (always 1) from rh_cdf computation. probit_transform_mod.f90 Renamed from quantile_distributions_mod.f90 Changed 'convert_' to 'transform_' for all public interfaces Colocated save variables used for dist_for_unit_sd Eliminated use of dimension 2 bounds arrays Avoided use of shape and scale key words for gamma probit_transform_mod.nml Renamed from quantile_distribitons_mod.nml assim_tools_mod.f90 Made test_ functions public to avoid unused function compiler error Removed unused variable declarations Eliminated use of dimension 2 bounds arrays Changed names for normal and probit subroutine calls perfect_model_obs.f90 Eliminated use of dimension 2 bound arrays lorenz96_tracer_advection/model_mod.f90 Removed unused declarations lorenz96_tracer_advection/work/input.nml Changed name to probit_transform_nml Changed default values in probit_transform_nml to avoid skipping over potential problems :# --- .../assimilation/adaptive_inflate_mod.f90 | 2 - .../assimilation/algorithm_info_mod.f90 | 80 +++--- .../modules/assimilation/assim_tools_mod.f90 | 144 +++++----- .../assimilation/beta_distribution_mod.f90 | 8 +- ...tion_mod.f90 => bnrh_distribution_mod.f90} | 174 +++++------ .../modules/assimilation/filter_mod.f90 | 25 +- .../assimilation/gamma_distribution_mod.f90 | 95 +++--- .../assimilation/neg_algorithm_info_mod | 80 +++--- .../assimilation/normal_distribution_mod.f90 | 108 ++++--- .../assimilation/one_above_algorithm_info_mod | 247 ++++++++++++++++ ...tions_mod.f90 => probit_transform_mod.f90} | 271 +++++++++--------- .../assimilation/probit_transform_mod.nml | 6 + .../perfect_model_obs/perfect_model_obs.f90 | 29 +- .../lorenz_96_tracer_advection/model_mod.f90 | 11 +- .../lorenz_96_tracer_advection/work/input.nml | 6 +- 15 files changed, 803 insertions(+), 483 deletions(-) rename assimilation_code/modules/assimilation/{rh_distribution_mod.f90 => bnrh_distribution_mod.f90} (75%) create mode 100644 assimilation_code/modules/assimilation/one_above_algorithm_info_mod rename assimilation_code/modules/assimilation/{quantile_distributions_mod.f90 => probit_transform_mod.f90} (79%) create mode 100644 assimilation_code/modules/assimilation/probit_transform_mod.nml diff --git a/assimilation_code/modules/assimilation/adaptive_inflate_mod.f90 b/assimilation_code/modules/assimilation/adaptive_inflate_mod.f90 index 41166b7ef5..fabb823100 100644 --- a/assimilation_code/modules/assimilation/adaptive_inflate_mod.f90 +++ b/assimilation_code/modules/assimilation/adaptive_inflate_mod.f90 @@ -722,8 +722,6 @@ subroutine update_varying_state_space_inflation(inflate, inflate_mean, inflate_s logical, intent(in) :: inflate_only real(r8) :: gamma, ens_var_deflate, r_var, r_mean -real(r8) :: diff_sd, outlier_ratio -logical :: do_adapt_inf_update if(inflate_mean <= 0.0_r8 .or. inflate_sd <= 0.0_r8) return diff --git a/assimilation_code/modules/assimilation/algorithm_info_mod.f90 b/assimilation_code/modules/assimilation/algorithm_info_mod.f90 index 905e0efd2c..f7fc8536ea 100644 --- a/assimilation_code/modules/assimilation/algorithm_info_mod.f90 +++ b/assimilation_code/modules/assimilation/algorithm_info_mod.f90 @@ -4,7 +4,7 @@ module algorithm_info_mod -use types_mod, only : r8, i8 +use types_mod, only : r8, i8, missing_r8 use obs_def_mod, only : obs_def_type, get_obs_def_type_of_obs, get_obs_def_error_variance use obs_kind_mod, only : get_quantity_for_type_of_obs @@ -54,14 +54,15 @@ module algorithm_info_mod contains !------------------------------------------------------------------------- -subroutine obs_error_info(obs_def, error_variance, bounded, bounds) +subroutine obs_error_info(obs_def, error_variance, & + bounded_below, bounded_above, lower_bound, upper_bound) !

It satisfies all of the test criteria for test_normal, test_gamma and test_beta. normal_distribution_mod.f90 Changed the min_quantile to 0. With current numerics this did not change any answers in the test suites and it eliminated the concern about compiler precision differences. Changed inv_weighted_normal_cdf to a function. Changed approx_inf_normal_cdf to a function and added extra unused arguments as an intermediate step to allow a common inv_cdf routine with function arguments. Renamed inv_normal_cdf to inv_std_normal_cdf since it only does the standard case. inv_std_normal_cdf now calls the generic inv_cdf providing the normal_cdf and the approx_inf_normal_cdf as function arguments. Created generic inv_cdf to do the inversion for any cdf. Temporarily stashed in normal_distributions_mod. Added test for quantiles of 0 or 1 in a bounded distribution to inv_cdf. beta_distribuiton_mod.f90 Added bounds arguments to inv_beta_cdf. Not yet implemented inv_beta_cdf now calls generic inv_cdf with beta_cdf and inv_beta_first_guess as function arguments. Added bounds arguments to beta_cdf. Not yet implemented. Added function inv_beta_first_guess to compute first guess for optimization. gamma_distribution_mod.f90 Added bounds arguments to inv_gamma_cdf. Not yet implemented. inv_gamma_cdf now calls generic inv_cdf with gamma_cdf and inv_gamma_first_guess as function arguments. Added bounds arguments to gamma_cdf. Not yet implemented. Added function inv_gamma_first_guess to compute first guess for optimization. bnrh_distribution_mod.f90 Adds extra bounds arguments to normal calls. These will be subsumed in defined types in the next changes. probit_transform_mod.f90 Removed unused variables from use statement. assim_tools_mod.f90 Added extra bounds arguments for cdfs for normal, beta and gamma. --- .../modules/assimilation/assim_tools_mod.f90 | 42 +++--- .../assimilation/beta_distribution_mod.f90 | 113 +++++---------- .../assimilation/bnrh_distribution_mod.f90 | 42 +++--- .../assimilation/gamma_distribution_mod.f90 | 117 +++++---------- .../assimilation/normal_distribution_mod.f90 | 136 +++++++++++++----- .../assimilation/probit_transform_mod.f90 | 16 +-- 6 files changed, 218 insertions(+), 248 deletions(-) diff --git a/assimilation_code/modules/assimilation/assim_tools_mod.f90 b/assimilation_code/modules/assimilation/assim_tools_mod.f90 index 4a6aa87570..d0073d95bf 100644 --- a/assimilation_code/modules/assimilation/assim_tools_mod.f90 +++ b/assimilation_code/modules/assimilation/assim_tools_mod.f90 @@ -8,7 +8,7 @@ module assim_tools_mod !> \defgroup assim_tools assim_tools_mod !> !> @{ -use types_mod, only : r8, i8, digits12, PI, missing_r8 +use types_mod, only : r8, i8, PI, missing_r8 use options_mod, only : get_missing_ok_status @@ -1124,7 +1124,7 @@ subroutine obs_increment_gamma(ens, ens_size, prior_mean, prior_var, obs, obs_va !

Changing to more consistent, efficient, and code sharing distribution modules with improved naming. This commit passes all tests for normal, beta and gamma and bitwise duplicates existing positive tracer tests for l96_tracer_advection. distribution_params_mod: New module that provides the defined distribution_params_type and the integer definitions of distribution types. filter_mod.f90: Changed to improved names for normal_distribution. algorithm_info_mod.f90: Distribution types are now defined in the distributions_param_mod rather than here. assim_tools_mod.f90: Switched back to the minimal argument list of the normal_cdf calls. bnrh_distributions_mod.f90: Switched back to minimal argument list for normal_cdf calls. beta_distribution_mod.f90: Added _params routines, beta_cdf_params, inv_beta_cdf_params, inv_beta_first_guess_params that take a distribution_params_type as input argument. Modified inv_beta_cdf to call the _params call, the other _params calls call the existing routines. gamma_distribution_mod.f90: Same as for beta. normal_distribution_mod.f90: Changed names to quantile for clarity in approx_inv_normal_cdf. Modified generic inv_cdf to take distribution_params_type input. Changed variable names to q for quantiles in inv_cdf generic routine. Changed p to q for clarity in inv_weighted_normal_cdf. Removed additional arguments from normal_cdf. Added normal_cdf_params needed for generic inv_cdf. Added approx_inv_normal_cdf_params for consistency with other distributions. approx_inv_normal_cdf back to standard arguments. Added inv_std_normal_cdf_params for generic inv_cdf. Clarified unpacking of parameters in inv_std_normal_cdf Added set_normal_params_from_ens to initialize the distribution_params_type. probit_transform_mod.f90: Changed integer constant naming for distribution types. Changed arguments in calls to normal_cdf. --- .../assimilation/algorithm_info_mod.f90 | 34 ++- .../modules/assimilation/assim_tools_mod.f90 | 20 +- .../assimilation/beta_distribution_mod.f90 | 59 ++++- .../assimilation/bnrh_distribution_mod.f90 | 32 ++- .../assimilation/distribution_params_mod.f90 | 31 +++ .../modules/assimilation/filter_mod.f90 | 6 +- .../assimilation/gamma_distribution_mod.f90 | 81 ++++++- .../assimilation/normal_distribution_mod.f90 | 218 ++++++++++++------ .../assimilation/probit_transform_mod.f90 | 39 ++-- 9 files changed, 365 insertions(+), 155 deletions(-) create mode 100644 assimilation_code/modules/assimilation/distribution_params_mod.f90 diff --git a/assimilation_code/modules/assimilation/algorithm_info_mod.f90 b/assimilation_code/modules/assimilation/algorithm_info_mod.f90 index f7fc8536ea..7ea474c664 100644 --- a/assimilation_code/modules/assimilation/algorithm_info_mod.f90 +++ b/assimilation_code/modules/assimilation/algorithm_info_mod.f90 @@ -17,6 +17,10 @@ module algorithm_info_mod use assim_model_mod, only : get_state_meta_data use location_mod, only : location_type +use distribution_params_mod, only : NORMAL_DISTRIBUTION, BOUNDED_NORMAL_RH_DISTRIBUTION, & + GAMMA_DISTRIBUTION, BETA_DISTRIBUTION, LOG_NORMAL_DISTRIBUTION, UNIFORM_DISTRIBUTION, & + PARTICLE_FILTER_DISTRIBUTION + implicit none private @@ -30,18 +34,8 @@ module algorithm_info_mod integer, parameter :: GAMMA_FILTER = 11 integer, parameter :: BOUNDED_NORMAL_RHF = 101 -!

Added subroutine beta_alpha_beta to compute the parameters of a beta from and ensemble. Moved the scaling into the cdf and inv_cdf routines. Not tested. gamma_distribution_mod.f90: Added subroutine set_gamma_params_from_ens that loads up a distribution_params_type given an ensemble. Not tested. distribution_params_mod.f90: Added an integer ens_size field. Added an additional allocatable r8 ens to hold the ensembles for the bnrh and particle filters. filter_mod.f90: Now using distribution_params_type for inflation. probit_transform_mod.f90: Now using distribution_params_type instead of defining the type for distributions itself. Most of the setting of params is done by the individual distribution modules (uniform is an exception for now). Only the bnrh is doing allocated storage for now and an explicit call to free the storage has been added. bnrh_distributions_mod.f90: Added bnrh_cdf_params and inv_bnrh_cdf_params subroutines that pass information through a distribution_params_type. bnrh_cdf_initialize_vector gets its info from a distribution_params_type now. New subroutine pack_bnrh_params allocates storage and inserts all values descriging the bnrh distribution in a distribution_params_type. New subroutine unpack_bnrh_params extracts this information. New function get_bnrh_sd returns the standard deviation of the ensemble that formed the bnrh. New subroutine deallocate_bnrh_params deallocates the storage used for the distribution_params_type. --- .../modules/assimilation/assim_tools_mod.f90 | 12 +- .../assimilation/beta_distribution_mod.f90 | 80 +- .../assimilation/bnrh_distribution_mod.f90 | 183 ++++- .../assimilation/distribution_params_mod.f90 | 2 + .../modules/assimilation/filter_mod.f90 | 7 +- .../assimilation/gamma_distribution_mod.f90 | 26 +- .../assimilation/neg_algorithm_info_mod | 38 +- .../assimilation/one_above_algorithm_info_mod | 38 +- .../assimilation/probit_transform_mod.f90 | 690 +++++++----------- 9 files changed, 538 insertions(+), 538 deletions(-) diff --git a/assimilation_code/modules/assimilation/assim_tools_mod.f90 b/assimilation_code/modules/assimilation/assim_tools_mod.f90 index e661f402c5..73ec4063fd 100644 --- a/assimilation_code/modules/assimilation/assim_tools_mod.f90 +++ b/assimilation_code/modules/assimilation/assim_tools_mod.f90 @@ -16,7 +16,7 @@ module assim_tools_mod find_namelist_in_file, error_handler, & E_ERR, E_MSG, nmlfileunit, do_nml_file, do_nml_term, & open_file, close_file, timestamp -use sort_mod, only : index_sort, sort +use sort_mod, only : index_sort use random_seq_mod, only : random_seq_type, random_gaussian, init_random_seq, & random_uniform @@ -71,7 +71,7 @@ module assim_tools_mod use quality_control_mod, only : good_dart_qc, DARTQC_FAILED_VERT_CONVERT -use probit_transform_mod, only : dist_param_type, transform_to_probit, transform_from_probit, & +use probit_transform_mod, only : transform_to_probit, transform_from_probit, & transform_all_from_probit use normal_distribution_mod, only : normal_cdf, inv_weighted_normal_cdf @@ -82,6 +82,8 @@ module assim_tools_mod gamma_gamma_prod use bnrh_distribution_mod, only : inv_bnrh_cdf, bnrh_cdf + +use distribution_params_mod, only : distribution_params_type implicit none @@ -389,10 +391,10 @@ subroutine filter_assim(ens_handle, obs_ens_handle, obs_seq, keys, & logical :: local_obs_inflate !

This put back in the computation of an adjusted amplitude for the tails from the likelihood. There is no likelihood any more, but when the likelihood routines were combined, a computation was done for the amplitude in either case. The amplitude should be one in inv_bnrh_cdf, but before there was a slight round-off error in some cases away from one. In the long-term, the amp_adj should be removed (as commented in code). This commit now reproduces earlier baseline for all tracer model cases. --- .../assimilation/bnrh_distribution_mod.f90 | 22 ++++++++++++------- 1 file changed, 14 insertions(+), 8 deletions(-) diff --git a/assimilation_code/modules/assimilation/bnrh_distribution_mod.f90 b/assimilation_code/modules/assimilation/bnrh_distribution_mod.f90 index 50ac3acec1..008a5291f6 100644 --- a/assimilation_code/modules/assimilation/bnrh_distribution_mod.f90 +++ b/assimilation_code/modules/assimilation/bnrh_distribution_mod.f90 @@ -383,7 +383,7 @@ subroutine inv_bnrh_cdf(quantiles, ens_size, sort_ens, & integer :: region, i, j real(r8) :: lower_state, upper_state, lower_mass, upper_mass, target_mass -real(r8) :: q(ens_size), curr_q, lower_q, upper_q, del_q, fract +real(r8) :: q(ens_size), curr_q, lower_q, upper_q, del_q, fract, amp_adj !

This was not a problem for gfortran which did not clear out the storage on the intent(out), but does not conform with the standard. Also modified the way in which distribution param allocated storage is cleared so it is done in the distribution_params_mod where that type is defined. Finally, released the allocated storage for the distribution param type used to transform the observation prior and posterior to probit space. This could have led to a memory leak in assim_tools for low-order models. --- .../modules/assimilation/assim_tools_mod.f90 | 4 ++- .../assimilation/bnrh_distribution_mod.f90 | 31 ++++++------------- .../assimilation/distribution_params_mod.f90 | 18 ++++++++++- .../assimilation/probit_transform_mod.f90 | 11 +++---- 4 files changed, 35 insertions(+), 29 deletions(-) diff --git a/assimilation_code/modules/assimilation/assim_tools_mod.f90 b/assimilation_code/modules/assimilation/assim_tools_mod.f90 index 8632209106..72a01dc383 100644 --- a/assimilation_code/modules/assimilation/assim_tools_mod.f90 +++ b/assimilation_code/modules/assimilation/assim_tools_mod.f90 @@ -83,7 +83,7 @@ module assim_tools_mod use bnrh_distribution_mod, only : inv_bnrh_cdf, bnrh_cdf, inv_bnrh_cdf_like -use distribution_params_mod, only : distribution_params_type +use distribution_params_mod, only : distribution_params_type, deallocate_distribution_params implicit none @@ -729,6 +729,8 @@ subroutine filter_assim(ens_handle, obs_ens_handle, obs_seq, keys, & call transform_to_probit(grp_size, obs_post(grp_bot:grp_top), dist_for_obs, & temp_dist_params, probit_obs_post(grp_bot:grp_top), .true., & bounded_below, bounded_above, lower_bound, upper_bound) + !

The observation, state, and inflation variables are all included in this single table. + +The new quantile options are read in from the table at runtime and then set in the module algorithm_info_mod.f90 in the DART/assimilation_code/modules/assimilation directory. This module provides routines that give information about details of algorithms for observation error sampling, observation increments, and the transformations for regression and inflation in probit space. + +For individual QTYs in DART, the user can specify the options such as the bounds, distribution type, filter kind, etc. for the obs_error_info, probit_dist_info, and obs_inc_info subroutines in algorithm_info_mod.f90 + +If the user does not use a QCF input table with the DART quantile conserving and probit transform filtering tools, then the default values for these options will be used for all QTYs. + +Table Composition +----------------- +Each QTY is specified in its own column, having 28 total control options. +These control options are divided into 3 main groups, which are the options used for the obs_error_info, probit_dist_info, and obs_inc_info. However, the user is able to specify different values for probit inflation, probit state, and probit extended state, resulting in 5 total groupings for the control options. + +The obs_error_info subroutine computes information needed to compute error sample for this observation. +For obs_error_info the input options are the two bounds (lower and upper). + +The probit_dist_info subroutine computes the details of the probit transform. +From probit_dist_info, the values needed are the bounds and the distribution type. These can be different for all three cases (inflation, state, and extended_state). + +The obs_inc_info subrotuine sets the details of how to assimilate this observation. +From obs_inc_info, the bounds, plus the filter_kind, rectangular_quadrature, gaussian_likelihood_tails, sort_obs_inc, and spread_restoration are needed. However, rectangular_quadrature and gaussian_likelihood_tails are only applicable with RHF. + +Full list of options: +Obs_error_info: bounded_below, bounded_above, lower_bound, upper_bound [4 columns] +Probit_dist_info: dist_type, bounded_below, bounded_above, lower_bound, upper_bound (x3 for inflation, state, and observation (extended state) priors) [15 columns] +Obs_inc_info: filter_kind, rectangular_quadrature, gaussian_likelihood_tails, sort_obs_inc, spread_restoration, bounded_below, bounded_above, lower_bound, upper_bound [9 columns] + +Customizing the Table +--------------------- +The table can be customized by either editing a YAML file (which is then converted to a tabular data file in .txt format by a Python script) or a Google Sheet spreadsheet (which is then downloaded in .csv format). The specifics of how to manually edit both formats will be detailed in the following sections. + +Regardless of which of these formats are used, the table consists of two headers. The first states the version # of the table being used; the most recent version of the table needs to be used to ensure compatibilty with DART. The current version # is 1. The second header lists the full set of input options, or all 28 column names in other words. + +Generally, the user will add and fill in one row for each bounded QTY. If a QTY is not listed in the table, the default values will be used for all 28 options. Therefore, the user will only need to add rows for QTYs that use non-default values for any of the input options. ** + +The majority of the input options are read in as logicals, and will need to be written in the format of either 'F' or '.false.' These include bounded_below, bounded_above, rectangular_quadrature, gaussian_likelihood_tails, sort_obs_inc, and spread_restoration. + +The actual numerical values of the bounds are read in as real_r8 types. These can be specified as reals or integers in the table. + +dist_type and filter_kind are read in as strings, which the possible values for are listed below: + +dist_type: +NORMAL_DISTRIBUTION +BOUNDED_NORMAL_RH_DISTRIBUTION +GAMMA_DISTRIBUTION +BETA_DISTRIBUTION +LOG_NORMAL_DISTRIBUTION +UNIFORM_DISTRIBUTION +PARTICLE_FILTER_DISTRIBUTION + +filter_kind: +EAKF +ENKF +UNBOUNDED_RHF +GAMMA_FILTER +BOUNDED_NORMAL_RHF + +The default values for each of the options are listed below: +bounded_below = .false. +bounded_above = .false. +lower_bound = -888888 +upper_bound = -888888 +dist_type = BOUNDED_NORMAL_RH_DISTRIBUTION +filter_kind = BOUNDED_NORMAL_RHF +rectangular_quadrature = .false. +gaussian_likelihood_tails = .false. +sort_obs_inc = .false. +spread_restoration = .false. + +Note that bounds set to -888888 are missing_r8 values. + +YAML File Usage +--------------- +This section will detail how to customize the qcf_table_template.yaml file and then utilize the yaml_to_table.py Python script to convert the YAML dictionary into a table in .txt format. + +First, the user needs to access YAML template file, located in DART/assimilation/programs/qcf_table/ +This template file is then to be copied into another file.

A matlab script -QCEFF_summary_results.m in this directory was run to create two files with the best case -localization parameters for each ensemble size: -QCEFF_SUMMARY_PRIOR adn QCEFF_SUMMARY_POST -The first of these has the results for the inflation cases with the smallest prior RMSE, while the -second has the results for the inflation case with the smallest posterior RMSE. The second -files were not used further here. - -A set of 10 runs from different initial conditions was performed for each of the ensemble sizes -with the optimal localization setting. This was done using the script summary_runs.csh in this -directory and generates output in the file QCEF_output_ten. - -The nameslist for these runs comes from INPUT.NML.QCEF.TEMPLATE. The only thing of interest is -the inflation settings which had inf_lower_bound = 0 and inf_upper_bound = 1000000. The inf_damping -was 0.9. The inf_sd_initial and inf_sd_lower_bound were set to 0.6 for the NONID and SQRT cases -but to 0.2 for the SQUARE and CUBE cases to try to stabilize the inflation. - - -This entire process was repated for the NONID, SQRT and SQUARE cases with the inflation lower bound -set to 1 (no deflation) and the upper bound set to 2. The damping was 0.9 and the -inf_sd_initial and inf_sd_lower_bound were the standard 0.6. The input.nml came from -REV.INPUT.NML.QCEF.TEMPLATE. These runs can be compared -to similar REV results in the DART_EXPLORATION branch/directory. The tuning was done with the script -rev_state_space_auto_filter.csh. The results are in REV_QCEF_RESULTS. The script -REV_QCEFF_summary_results.csh extracted the best cases and wrote them to -REV_QCEFF_SUMMARY_POST and REV_QCEFF_SUMMARY_PRIOR. The 10 different runs were created -using rev_summary_runs.csh and written to REV_QCEF_output_ten. These are the results that are -used for the figure results for the QCEF paper part 2. - -Note that there are a handful of cases that fail when generating the ten cases. This is noted -by the number of steps in the output files (should be 5500 for success). Failures only occured -for the SQUARE forward operator. - -Note 2: One of the cases in the output_ten files for each ensemble size should be idential to -the tuning run. However, in some cases the tuning runs were done for the first on the ten -perfect_ics file, and in some for the tenth. This should not impact the validity of the result -in any way but could be confusing when trying to understand how the cases were generated. - -Several plotting scripts are available here. -plot_ten_nonid_rmse.m, plot_ten_sqrt_rmse.m, and plot_ten_square_rmse.m for the different cases. -These also access comparable results from the DART_EXPLORATION directory (EAKF, EnKF, RHF -with standard regression).
