Coupled simulation with deadveg branch (f2000.ne30_t232.BGC_CROP.deadveg) #53

Open olyson opened 4 months ago

olyson commented 4 months ago

Description: Coupled simulation with the deadveg branch. This is the coupled version of ctsm51_ctsm51d166deadveg_1deg_CRUJRA_FLDS_ABsnoCDE_blk_A5BCD_1850 (Issue #52 )

Purpose is again to see if increased vegetation at high northern latitudes can lower albedo in spring/early summer and cause earlier melt-out of the snowpack, and warm up the simulation at these latitudes.

Sandbox: Locally: /glade/work/oleson/cesm2_3_alpha16g_deadveg. This is the cesm2_3_alpha16g tag with clm externals updated to the deadveg branch (https://github.com/olyson/ctsm/tree/deadveg).

Extra details:

CLM Initial Conditions: Currently setup using the end of the 1850pAD version of this configuration. Could also wait for the historical using this configuration and using an initial file from that circa-year 2000. But either way we'd be transitioning from CRUJRA to coupled model forcing, so I'm inclined not to wait for the historical. Opinions, @slevis-lmwg , @wwieder ?

96 years completed.

I say go for it. Could always run again with different finidat when it's available.
