Following changes were committed to the NEMSfv3gfs and FV3 repositories:
Ticket #61047 <https://vlab.ncep.noaa.gov/redmine/issues/61047>: Merge FV3
chemistry development branch into master branch and two other fixes
The latest updates required to run the coupled NEMS app FV3GFS-GSDCHEM are
committed. The updates include:
1. Introduced the capability to generate NGAC-consistent diagnostic output
for atmospheric chemistry. The diagnostic values are imported from coupled
chemistry component via coupling fields.
2. Updated support for coupled chemistry component.
-Bug fix in m2_rain and m2_sol in GFDL microphysics subroutine
-Improved error checking and proper handling of error conditions from
ESMF/NUOPC logical functions.
-Proper initialization of coupled fields
This ticket also includes two code changes not directly related to
1. Issue #60767 <https://vlab.ncep.noaa.gov/redmine/issues/60767> - bit for
bit in dump files for cap. The ESMFPP_RegridWrite(), implemented in
FV3/cpl/module_cap_cpl.F90, does not include settings for bitwise
reproducibility of regridded ESMF Fields. This is fixed by setting the
termorderflag flag to ESMF_TERMORDER_SRCSEQ to ensure bit-for-bit
2. Bug fix for diagnostic field dt3dt(i,k,7) and dt3dt(i,k,8) when ldiag3d
is turned on. (code changes are listed in #61047
Above code changes have no impact on current standalone NEMSfv3gfs
regression test baseline. Regression test passed on wcoss (phase1/2, cray
and dell), theia and gaea.
