That is great! My grid size is 30 km instead of 36 km, and I think the difference is trivial. I will read the format and modified it to my own grid. <br>Thanks a lot!<br><br>Hao<br><br><div class="gmail_quote">On Wed, May 5, 2010 at 1:52 PM, Huddleston, John <span dir="ltr"><<a href="mailto:Huddleston@cira.colostate.edu">Huddleston@cira.colostate.edu</a>></span> wrote:<br>

<div>Hi,<br>
I have a 2D data set with uneven Lon and Lat distribution. I notice that the GRIB data for GrADS has even grids, so I am wondering whether it is possible to display this data set on GrADS? Thanks for help!<br>
