GitHub issues

  • None new.

Update from Cheryl on CCPP in CGD

  • CGD has officially announced that CAM7 will adopt CCPP to manage their physics
  • Likely starting next year. Officially "January" but there is no CCPP framework person in CGD.
    • Steve has been offered contract work, but will not be full time
    • Starting the process of opening a new position
  • Let's have more discussion to work together on getting CGD and DTC interests converged!

Interstitial Scheme Changes

There has been A LOT of discussion about improving the interoperability of interstitial schemes amongst both DTC and the larger CCPP Physics Management group. In addition, there has been a longstanding desire to reduce the amount of interstitial schemes needed to make a working suite. Therefore:

  • DTC team has been examining the current crop of interstitial schemes with a critical eye toward reducing/reorganizing them: See https://docs.google.com/spreadsheets/d/1_Zw5B49QM_HHgMhstwz_8xFkG9ygxvAkxKmpm2ECP28/edit#gid=368751223
  • Some of the code found in interstitial schemes should be able to be handled by autogenerated code from the framework
  • Key functionalities to move to the framework include:
  • Tendency handling and application; all schemes should return tendencies; SDFs can specify process-/time-split and the framework "does the right thing"
  • Constructing arrays of constituents to be operated on by schemes (e.g. vertically-diffused tracers, convectively-transported tracers, ...)
  • Automatically handling array size expansion (e.g. host provides (i,k) arrays, but scheme needs (i,j,k) arrays)
  • Taking over what is in GFS_debug.F90 (writing out all vars used by current suite -- framework knows the location in memory of all variables, so why not?)

Other business

  • Mike began updating ccpp-framework Wiki pages, still a work in progress
  • Mike is experimenting with adding more pytest tests to tests/ directory, will document the process for future users.
    • No updates from last week, been busy wrapping up UFS SRW V2.1 release
