Use of CCPP for surface flux computations on the exchange grid?

• Presentation by Ufuk Turuncoglu/Rocky Dunlap followed by Q&A
  • Slides: https://docs.google.com/presentation/d/11bprCmMyeB2Jgrnx9BJhS5VCYErAIJEFGEkeR0oURa0/edit#slide=id.g10da078906e_0_294
• Initial implementation of calling CCPP from the CMEPS mediator to calculate atmosphere-ocean fluxes on the atmosphere grid or the exchange grid
• Not using ccpp-framework yet, calling ccpp-physics schemes directly
  • This creates a big overhead, looking for better ways
  • If the framework is used, need a way to handle the fields required by the physics (allocation, initialization)
  • Simplifying and splitting apart some of the complicated surface physics will make this a bit easier
  • As a first step, make the CMEPS mediator a host model and call the physics through the framework, worry about the allocation/initialization of data later

capgen unification

• GitHub projects page describing the unification efforts: https://github.com/NCAR/ccpp-framework/projects/3
• capgen tasks and efforts (need permission): https://docs.google.com/spreadsheets/d/1u_yA9PyG9aVHMvlXDjmVIaxcgaKo2nR7NPVV2Kmw0Ck/edit#gid=0
• Dom added test to address #369, fixed #397 (all that is left is to merge #428) and previously #359

CCPP Visioning Workshop

• Any update?

CCPP requirements document

• Current documentation is here:
  • Historical (frozen) document
  • DTC CCPP requirements page
