Hello Ashraf.   The domain was iy =100, jx =150 for DX = 30 km.  Also  I used.

      parameter(ntypec=10)      ! Global topo/landuse data resolution (min)
      parameter(ntypec_s=10)    ! Global topo/landuse data resolution (min)

I have the SOILCAT.02  in my data directory along with the 10 minute data.  Was I supposed to set
ntypec_s = 2?

Thanks

Greg

Hi Greg,

  Some other issues need to be considered, 1) the resolution of soil
texture file; 2) the resolution of the land-use. what is the map factor
inside your domain?

   How many points you have in your domain? Any way, I'm preparing for
Dust sub-gird scheme version  which will help with the high resolution
run.
