Description:
Test Sturm 1997 calculation of snow thermal conductivity
I've added the snow conductivity calculations from Sturm et al. provided by in this CTSM discussion and described for single point runs by Dutch et al 2022. Many thanks to @AdrienDams for doing some preliminary tests with this globally.
Source mods are here /glade/u/home/wwieder/CTSM/src/biogeophys/SoilTemperatureMod.F90. @olyson, do you want to try a land only case with this SourceMod to investigate soil temperature impacts and arctic vegetation survival?
