Tom,
ngrids is a dimension only, the grid_number should be at the bottom of the
cdl file:
grid_number = 236, 255 ;
I attached ruc2.cdl in case your copy was somehow corrupted. I used
ncdump on a ruc2.nc file today and located grid_number ok, maybe the file
Don sent was corrupted. This happens once in a while when there is no
disk space to write the ruc2.nc file. These files are large:
