Release Notes

Bundle CCPP-SCM Version 2.0

The Bundle CCPP-SCM v2.0 contains the CCPP v2.0 and the SCM v2.1.

CCPP Version 2.0 Parameterizations

  • GFS RRTMG shortwave and longwave radiation
  • GFS ozone
  • GFS Zhao-Carr microphysics
  • GFDL microphysics
  • GFS scale-aware mass-flux deep convection
  • GFS scale-aware mass-flux shallow convection
  • GFS hybrid eddy diffusivity-mass-flux PBL and free atmosphere turbulence
  • GFS orographic gravity wave drag
  • GFS convective gravity wave drag
  • GFS surface layer
  • GFS Noah Land Surface Model
  • GFS near-sea-surface temperature
  • GFS sea ice
  • Additional diagnostics and interstitial computations needed for the GFS suite

CCPP Version 2.0 Framework

  • Metadata standards for defining variables provided by the host application (in this case SCM) and needed by each parameterization
  • CCPP_prebuild_script to parse host model and parameterizations metadata tables, compare the two and alert if incompatible, manufacture Fortran code for host model and physics caps, and generate makefile snippets
  • New format for the Suite Definition File that allows choosing parameterizations at runtime
  • Ability to automatically run the init and finalize routines of all parameterizations
  • Split process for initialization of CCPP Framework (call ccpp_init) and CCPP Physics (call ccpp_physics_init)
  • Changes to API: previous call ccpp_run is now call ccpp_physics_run and can take group_name and scheme_name as optional arguments
  • Improved error handling
  • Performance improvement to speed up the initialization

SCM Version 2.1

  • Cmake build system to compile needed NCEP libraries, SCM, CCPP framework, and parameterizations
  • Metadata available for CCPP cap creation
  • Test cases
    • Tropical Warm Pool - International Cloud Experiment (TWP-ICE) maritime deep convection
    • Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) continental deep convection
    • Atlantic Stratocumulus Transition EXperiment (ASTEX) maritime stratocumulus-to-cumulus transition
    • Barbados Oceanographic and Meteorological EXperiment (BOMEX) maritime shallow convection
    • LES ARW Symbiotic Simulation and Observation (LASSO) for May 18, 2016 (with capability to run all LASSO cases) continental shallow convection
