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!

ice_tau_abs_od(:,1:ncol,:) = 0._r8
cld_abs_od(:,1:ncol,:) = 0._r8

Thanks for writing, Yu-Tong. At this time, CESM1.2 and iCESM1.2 are only supported for deep time paleoclimate and water isotope applications, respectively. Are you using the model for one of those purposes? If so, I will direct this to the appropriate forum. If not, I apologize that we are no longer able to provide support for CESM1.2; we encourage you to update to the CESM2 series. See Support Policy | Community Earth System Model for support details.
