I'm using WRFV4.6.0,and I can't find SF_SURFACE_MOSAIC in my namelist.input file,and still can't find it when I checked the rsl.out.0000 file,so how to find it?if I can't find it,does this mean the SF_SURFACE_MOSAIC is set to the default value of 0?Is it that landusef does not play a role in the simulation, but lu_index dominates instead?
