CESM3-SP test (b.e23_alpha16b BLT1850 ne30_t232 034SP) #6

Open wwieder opened 10 months ago

wwieder commented 10 months ago

Description: Same as b.e23_alpha16b.BLT1850.ne30_t232.034 (cloned) but with CLM satellite phenology (SP) instead of BGC. Purpose is 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.

@olyson @adamrher This case includes some src.cam mods. Initially I included them in my F-case #13 and failed due to a history var not appearing in the master list. I have decided to omit these mods altogether in #13, unless you recommend otherwise.

Hi @slevis-lmwg the SourceMods in https://github.com/NCAR/amwg_dev/issues/361 should be included. They provide Ri based diffusion above where clubb is active. But I don't expect this to have a first order impact on the radiative balance.

Looks liken you're basing these runs on coupled baseline 34, which is fine, but note 34 is a bit colder than our more recent runs (38-44). Moving targets are always a challenge ...
