[RegCNET] Floating point exception when using the dust model

[Gregory Jenkins]

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
