Agenda

• capgen.py progress
• Transition to capgen.py
• Process for creating a master cross-lab standard name resource
• NCEP Central Operations WCOSS Implementation Standards
• Other business

capgen.py process

• What is the process forward with getting capgen ready for the UFS?

Transition to capgen.py

• PR Use assumed-size arrays in CCPP, Fortran/metadata consistency fixes in CCPP (https://github.com/ufs-community/ufs-weather-model/pull/527) was merged on April 30
  • A few fixed array dimensions were forgotten, Grant will fix some in a forthcoming ccpp-physics PR
  • Using assumedd-size arrays helped to identify and fix a few bugs already (part of #527)
  • We need to watch out for future PRs to follow the new rules/guidelines (sent to physics developers)
    • Order of arguments in subroutine must be same as in metadata (why?)
    • Use assumed-size array dimensions where possible

Process for creating a master cross-lab standard name resource

• PRs for ccpp-physics and CCPPStandardNames are there:
  • https://github.com/NCAR/ccpp-physics/pull/637 - some b4b issues with SCM to resolve, not tested with UFS yet
  • https://github.com/ESCOMP/CCPPStandardNames/pull/13 - now we need to engage NCAR and others?

NCEP Central Operations WCOSS Implementation Standards

• https://www.nco.ncep.noaa.gov/idsb/implementation_standards/Implementation%20Standards%20v10.2.pdf?
