+One-line Summary: Make RRTMGP default radiation in CAM7
+Github PR URL: https://github.com/ESCOMP/CAM/pull/1178
+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+
+. Issue #1143 - turn RRTMGP on by default for CAM7 + some namelist defaults
+
+. Remove some tests that added rrtmgp to the cam7 configuration.  Not
+  needed since rrtmgp is now the default in cam7.
+
+. Remove test of old cam7 development configuration (32 levels) which is no
+  longer needed.
+
+. Remove 13 month F2000climo test.  This was originally created to make
+  sure we didn't make changes that hurt the performance of our production
+  configuration for CMIP6 simulations.  This is no longer needed.
+
+. Issue #1154 - Create at least one CAM7 regression test on izumi
+  - add ERP_D_Ln9.ne3pg3_ne3pg3_mg37.FLTHIST.izumi_gnu.cam-outfrq9s
+
+
+Describe any changes made to build system: none
+
+Describe any changes made to the namelist:
+
+. change default value of seasalt_emis_scale to 0.75 for cam7 (both lt and mt)
+  This is a cam7 tuning mod from issue #1143
+
+. update ubc_file_path for cam7 (lt only) to 
+  atm/cam/chem/ubc/b.e21.BWHIST.f09_g17.CMIP6-historical-WACCM.ensAvg123.cam.h0zm.H2O.1849-2014_c240604.nc
+
+List any changes to the defaults for the boundary datasets:
+
+. update ubc_file_path for cam7 (lt only) to 
+  atm/cam/chem/ubc/b.e21.BWHIST.f09_g17.CMIP6-historical-WACCM.ensAvg123.cam.h0zm.H2O.1849-2014_c240604.nc
+
+Describe any substantial timing or memory changes: none
+
+Code reviewed by: cacraig, peverwhee, sjsprecious
+
+List all files eliminated:
+
+cime_config/testdefs/testmods_dirs/cam/outfrq1d_14dec_ghg_cam7/*
+. test removed
+
+List all files added and what they do:
+
+cime_config/testdefs/testmods_dirs/cam/outfrq9s_eoy/*
+. mods for a test like outfrq9s, but add RUN_STARTDATE="1999-12-31" and
+  START_TOD="82800" so that the run goes over the end of year boundary.
+
+List all existing files that have been modified, and describe the changes:
+
+bld/configure
+. set default radiation package for cam7 to rrtmgp
+
+bld/namelist_files/namelist_defaults_cam.xml
+. change default value of seasalt_emis_scale to 0.75 for cam7 (both lt and mt)
+  This is a cam7 tuning mod from issue #1143
+
+bld/namelist_files/use_cases/1850_cam_lt.xml
+. update ubc_file_path to 
+  atm/cam/chem/ubc/b.e21.BWHIST.f09_g17.CMIP6-historical-WACCM.ensAvg123.cam.h0zm.H2O.1849-2014_c240604.nc
+
+cime_config/testdefs/testlist_cam.xml
+. These tests which added rrtmgp to cam7 are no longer needed.
+  ERP_D_Ln9.ne30pg3_ne30pg3_mg17.FLTHIST.*_*.cam-outfrq9s_rrtmgp
+  SMS_D_Ln9.ne30pg3_ne30pg3_mg17.FMTHIST.*_*.cam-outfrq9s_rrtmgp
+. Remove old cam7 configuration test which is no longer needed
+  ERS_Ld3.f10_f10_mg37.F1850.izumi_gnu.cam-outfrq1d_14dec_ghg_cam7
+. Move these low resolution tests from derecho to izumi

+  ERS_Ln9_P24x1.mpasa480_mpasa480.F2000climo.izumi_gnu.cam-outfrq9s_mpasa480
+. Add this low resolution CAM7-LT test to izumi
+  ERP_D_Ln9.ne3pg3_ne3pg3_mg37.FLTHIST.izumi_gnu.cam-outfrq9s
+. Remove 13 month cam6 test which is no longer needed.
+  SMS_Lm13.f10_f10_mg37.F2000climo.derecho_intel.cam-outfrq1m
+
+cime_config/testdefs/testmods_dirs/cam/outfrq9s_mg3_default/shell_commands
+. add '-rad rrtmg' to CAM_CONFIG_OPTS.  This test is using a non-standard
+  configuration of cam7, and this override is needed since the default
+  radiation scheme for cam7 has changed to rrtmgp.
+
+
+If there were any failures reported from running test_driver.sh on any test
+platform, and checkin with these failures has been OK'd by the gatekeeper,
+then copy the lines from the td.*.status files for the failed tests to the
+appropriate machine below.  All failed tests must be justified.
