CCPP Framework Meeting Minutes 2021 08 24

Agenda

New business

Old business

• Transition to capgen.py
• Dictionary of standard names

Transition to capgen.py

• Dom updated main from feature/capgen to simplify future work, and merged main back to feature/capgen
  • https://github.com/NCAR/ccpp-framework/pull/391 (merge feature/capgen into main)
  • https://github.com/NCAR/ccpp-framework/pull/398 (merge main back into feature/capgen)
• NCAR will create an issue to express that they want to also use the ccpp-framework main branch in the near future
  • NOAA will plan to transition to a dedicated branch
  • This requires ironing out a testing plan for the main branch, which is somewhat similar to the ongoing ccpp-physics governance discussion
  • Liga to present a few of the ccpp-physics governance slides at this meeting

Dictionary of standard names

• Necessary to agree on correct units for dimensionless variables; Dom created issues in ccpp-framework and ESCOMP CCPP standard names:
  • https://github.com/NCAR/ccpp-framework/issues/397
  • https://github.com/ESCOMP/CCPPStandardNames/issues/19
  • https://github.com/ESCOMP/CCPPStandardNames/pull/21 (Update standard name rules with rules for units)
    • Needs approval from Ligia and Grant for merging
• Status of "the" PR https://github.com/ESCOMP/CCPPStandardNames/pull/13?
  • Recent updates of PR 13 (based on PR 16 - updated rules) requires follow-up PRs for ccpp-physics, fv3atm, scm
  • Need to identify which variables are specific to a model or a single scheme - what was the final decision and what has been done so far?
    • From last week: Merge PR 13, then convert sections into categories, then add capability to query host model metadata to create the filtering capability
