Hello everyone, I am trying to run an experiment with CESM 1.2.2 using the LW-off option, but I am having trouble turning it off. I attempted to modify some .f90 files (following), but it seems not to work.
Could anyone give me guidance on how to properly disable the longwave radiation in this CESM version?Thankyou!
