Description

The current code in fv3atm has a bug when running nested models. The atmos_model_nml section, which contains options such as ccpp_suite, blocksize, fhdiag, is currently read in fv3atm before atmosphere_init is called. This is required, because atmosphere_init needs ccpp_suite.

However, the capability to read the correct namelist for the nests is only turned on during atmosphere_init. The nests currently read the wrong namelist section atmos_model_nml), namely that of the parent. This means that all values in that section are potentially wrong: ccpp_suite, blocksize, fdiag, ...

For a detailed description of the solution, see NOAA-GFDL/GFDL_atmos_cubed_sphere#86.

This bug is fixed in PRs NOAA-GFDL/GFDL_atmos_cubed_sphere#86 and #263.
