Re: NARCCAP Resolution Problem

Hi Eric,

If all you want to do is plot the data, you don't need to regrid it. If you
attach the lat & lon arrays to your y1 variable as @lat2d and @lon2d
attributes, you should be able to pass y1 to gsn_csm_contour_map_ce as-is.

For a more elaborate example, here's the general-purpose script that we use for
plotting NARCCAP data during the quality-checking process:
http://www.narccap.ucar.edu/contrib/tools/plot.ncl

The triple2grid function reassigns each of the input points to the nearest
output gridcell, which is almost certain to produce gaps unless the output
gridcells are bigger than the average spacing of the input data. If what you
want is to fill in a regular lat/lon grid at some arbitrary resolution using
values based on data from a curvilinear grid, then I would suggest using an
interpolation function like rcm2points instead.

Cheers,

--Seth
