Extract a Subset of NARR data and Map Projection

[Vinay]

Hi

I have a problem with extracting a subset of NARR data and displaying
in any required map projection. The data is distributed by ESRL
(http://www.esrl.noaa.gov/psd/data/narr/format.html) in a Lambert
Conformal projection as irregular grid of dimensions 349x277 with the
projection parameters. I want to transform the image into different
projection, make it to a regular grid and extract my region of
interest whose lat/lon is known. I tried several methods and also
followed many tips from http://www.idlcoyote.com/map_tips/map_tips.php
....but no luck.

Any suggestions/tips on this will be a great help.

By the way I am using IDL 7.0.6.


Thanks
