Re: Plot NARR data on cylindrical equidistant

Dave,

Please see example 3 at:

   http://www.ncl.ucar.edu/Applications/ice.shtml

for examples of plotting your data using 2D lat/lon arrays, and
not having to regrid them. Of particular note are the lines:

   hi_at_lon2d = lon2d
   hi_at_lat2d = lat2d

which you will need in your code.

You should be able to use the same method for a Cylindrical
Equidistant projection.
