CCPP Framework Meeting Minutes 2021 01 05

Agenda

capgen.py progress
- Advection feature (w/ NRL)
- Organization for code modularity (e.g., diagnostic code)
Transition to capgen.py
Other business

Need plan yet how to handle optional arguments (Dom to reach out to developers - EMC, GSL, Robert & Dustin, Phil, NRL)
DTC needs to develop a mechanism to avoid using the field_table - use an internal field table approach, similar to the internal input file? --> Dom to create issue in UFS

Updated DTC timeline and resource chart (https://docs.google.com/spreadsheets/d/1XbSF1ejYcPMrVtZtk1OSiMX-vI5srLkwEUhyAirGr8k/edit?usp=sharing)
Things that need to happen for transitioning UFS to capgen.py (https://docs.google.com/document/d/1M3mCO3ESR9OJqLyUbQf-ahJtmfmGKilZlWaBTxsfMRk/edit?usp=sharing)
timestep_init and timestep_final implementation will be merged mid January
Transition at the end of February
Dictionary of standard names:

- largely in agreement, a few clarifications and suggestions for abbreviations, what is the default if not explicitly spelled out
- binary mask versus other types of masks (three categories, ...)
- flag, option, switch, control, ... --> use flag for boolean true/false, control for integer
- CCPP error handling variables - better standard names
- need a convention on how to order the components that make up a standard name: variable name, at xyz, for abc, ...; where does "tendency_of" go?
- CF does define rules for the order of standard name components
Is the active attribute implementation in ccpp_prebuild.py a good one, or the implementation in capgen.py? What is the best way forward?
- current implementation in ccpp_prebuild.py: https://ccpp-techdoc.readthedocs.io/en/latest/
