Research direction

Start by comparing this request with issue #79 and inspect SourceMods/src.drv/shr_flux_mod.F90 plus user_nl_cam in the listed case directory. Use the CESM sandbox and case links to reproduce the run, then review the linked diagnostics to confirm that SWCF increases in magnitude with the 25% LHFLX reduction and revised clubb_gamma_coef.

Written by the indexing model from the issue text.

Description

Purpose:
Increase SWCF (more negative) in run with reduced LHFLX
(similar to what we did in https://github.com/NCAR/amwg_dev/issues/686)


Description:

same as 156 (#79)

  • using 25% reduction in latent heat flux
