CCPP Framework Meeting Minutes 2021 06 29

Agenda

• Standardized way to read tabulated data in CCPP schemes?
• Update on standard names
• Scheme-specific internal diagnostics

Standardized way to read tabulated data in CCPP schemes?

• deferred to when Steve and Andrew are back

Dictionary of standard names

• Several standard names in PR that mean the same thing, and a few more open questions
  • See https://github.com/ESCOMP/CCPPStandardNames/pull/13
  • Grant to send an email to Cheryl who will ask in her science group
• PRs for host models not yet created
  • Grant will create PRs once the remaining questions are addressed

Lumping scheme-specific internal diagnostics together

• See https://github.com/NCAR/ccpp-physics/pull/679
• This approach makes sense but we should strive for consistency and update the documentation to explicitly allow this
• Not consistent with plans for the future (diagnostic output from CCPP)
• Dom should update the PR with information on what is in the array (get input from Eric)

Other business

• Training for CAM scientists to port their parameterizations to CCPP, a few of them will start this work soon
  • Training material: ... PLEASE UPLOAD CHERYL
• Thompson MP development meeting
  • Scheme should be run with smaller time step
  • Can either use CCPP subcycling capability or implement an inner loop inside the scheme itself
  • Is subcycling capability in CCPP too prone to errors (because changes need to be made inside the scheme as well, at least until we automatically pass the correct time step down to the scheme)
