Hi, I want to nudge observed surface heat flux (sensible heat flux and latent heat flux) in CAM4. I know that the compset FSDCHM can nudge winds and temperature (U,V,T maybe also nudge PS?) in CAM4. Since i have found the get_met_srf2 subroutine in dynamics/fv/metdata.F90 may overwrites these surface heat flux inputs, I wonder is there a way to nudge surface heat flux in cam?
