Sturm_vegMods + new SNICAR + SNICAR param changes (ctsm51_ctsm51d150_ne30pg3ne30pg3mg17_GSWP3V1_ABCDE_blk_ABCD_1850AD) #37

Description: Same as ctsm51_ctsm51d150_ne30pg3ne30pg3mg17_GSWP3V1_ABCDE_1850AD but adding on changes to SNICAR parameters per single point studies in Issue #36 . Motivation is that we want to see the effects of lower snow albedo. Just running an AD for now. Note that this uses ctsm5.1.dev150. NOTE: xdrdt=2 setting was not actually implemented due to a coding issue.

Extra details: My case name lengths are out of control, so I've designated this combination simulation as ABCDE_blk_ABCD, where the first ABCD is: A - SturmSnowtk (implemented via src.clm/SoilTemperatureMod.F90) B - decidphenotrig (implemented via src.clm/CNPhenologyMod.F90) C - frootleaf (implemented via ctsm51_params.c211112.nc.ABCD_blk_ABCD.nc) D - FUNfracfixers (implemented via ctsm51_params.c211112.nc.ABCD_blk_ABCD.nc) E - new SNICAR blk - snicar_snobc_intmix = .true. (implemented via namelist, per Issue #36 ) and the next ABCD is (per Issue #36 ) A - xdrdt = 2 (implemented via ctsm51_params.c211112.nc.ABCD_blk_ABCD.nc) B - scvng_fct_mlt_sf = 0.5 (implemented via ctsm51_params.c211112.nc.ABCD_blk_ABCD.nc) C - snw_rds_refrz = 1500 (implemented via ctsm51_params.c211112.nc.ABCD_blk_ABCD.nc) D - fresh_snw_rds_max = 400._r8 (implemented via namelist)

See discussion in https://github.com/NCAR/LMWG_dev/discussions/3 and Issue #36 AD spunup to 2.69% disequilibrium, 280 years pAD spunup to 7.73% disequilibrium, 440 years Complete for now.

Just to note that because of the recent problems on cheyenne this has been stalled in the queue since 11/25/23.
