Now I use CAM5 in CESM1_0_4 to study the mechanical and thermal forcing of the Tibet Plateau (TP). FV dynamic core is employed.
First, I want to get the mechanical influence of the Tibet Plateau. So I design to shut down the surface topography of TP. The variable PHIS in surface topography file in CESM should be set as zero. But variables SGH and SGH30 in this file, I don’t know their utility in CAM5 model. Should I also set them to zero?
Secondly, I want to set the surface sensible heat flux into the atmosphere to zero over TP region, and the land surface energy budget is not changed. But I don’t know in which Fortran code file contains this term. Please tell me the targeted code file.
