Re: NCL and swath data?

You can plot any swath data directly by assigning
the 2D lat/lon arrays

(a) Example: hdf4sds_5.ncl

          res@sfXArray = lon2d
          res@sfYArray = lat2d

(b) x@lat2d = f->Latitude ; (:,:)
          x@lon2d = f->Longitude

Se also: hdf4eos_5.ncl,

Note: If the file is hdf-eos then you may have to access
       the data by appending .he2 or /hdfeos to get the lat/lon arrays
