GSWP3 + d166deadveg branch + init tsoisno=272K (ctsm51_ctsm51d166deadveg_ne30pg3ne30pg3mg17_GSWP3V1_ABsnoCDE_blk_A5BCD_1850AD, pAD) #57

Description: Same as #52 but with GSWP3 forcing and using ne30 grid. Spinup of the deadveg branch (PR #2348). Intended to create initial conditions for next round of coupled simulations. Include init tsoisno=272K (Issue #2338)

Extra details: I've designated this combination simulation as ABsnoCDE_blk_A5BCD, where the first ABsnoCDE is: A - SturmSnowtk (implemented in the default lnd_in) Bsno - snow5d_thresh_for_onset = 0.2 (implemented by default in ctsm51_params.c240208.nc, other CNPhenologyMod.F90 mods back to defaults) C - frootleaf (implemented by default in ctsm51_params.c240208.nc) D - FUN_fracfixers (implemented by default in ctsm51_params.c240208.nc) E - new SNICAR (implemented in the default lnd_in) blk - snicar_snobc_intmix = .true. (implemented in the default lnd_in) and the next A5BCD is A5 - xdrdt = 5 (implemented by default in ctsm51_params.c240208.nc) B - scvng_fct_mlt_sf = 0.5 (implemented by default in ctsm51_params.c240208.nc) C - snw_rds_refrz = 1500 (implemented by default in ctsm51_params.c240208.nc) D - fresh_snw_rds_max = 400._r8 (implemented by default in ctsm51_params.c240208.nc)
