This PR will address zero cloud fraction issue for RRFS ensemble members using GFS PBL and G-F convection by adding SGS cloud to ccpp SDF and changing conv_cf_opt to Xu-Randall for convective cloud fraction computation for those members.
The change to ccpp-physics is to add conv_cf_opt as an input namelist parameter for runtime switch (conv_cf_opt=1 for GFS PBL members).
ccpp-physics issue:
#185
Several tests for a single case (init 2023/05/10/06Z) have been performed by:
Here are total/low/medium/high cloud fractions and downward short wave radiation flux at surface:
