[ncl-talk] get_dst_grid_info

Dear Xueming,

As Karin suggests, we need a little more information.  The
"get_dst_grid_info" is coming out of the ESMF regridding, but it's an
internal routine that nobody knows about.

My guess is that you haven't provide a "destination" lat/lon grid to regrid
to.  It looks like you set:

opt at DstGridType  = "rectilinear"

or something like that, but this is not enough information. You need to
explicitly provide the information to regrid to, like:

opt at DstGridType = "0.5deg"


opt at DstGridType = "1x1"    ; 1 x 1 degree

or you need to provide the actual lat/lon arrays for regridding:

;---Create the destination lat/lon grid
    lat = fspan( 53.2420, 85.4022,nlat)
    lon = fspan(135.7750,258.1880,nlon)

    opt at DstGridType          = "rectilinear"
    opt at DstGridLat           = lat
    opt at DstGridLon           = lon

Please see the ESMF regridding examples page:
