Dear all,

I am sorry to trouble you, but I encounter a SURFACE data problem when I run the new RegCM4.1 model with CLM scheme. The problem occurs when I do this step: ../Bin/terrain regcm.in.  It seems that there is not "SURFACE/GTOPO_DEM_30s.nc" data. But I find there is not GTOPO_DEM_30s.nc data in present RegCM4 SURFACE DATA file. I will be very grateful to you for any help.Thanks very much in advance.
