</blockquote><div>GrADS do not handle gridded data in ASCII format. You will have to write a simple program to have your data converted to a format that GrADS can read first. Here is a recipe using Fortran:</div><div><br>

<div style="word-wrap:break-word">Dear All,
<div>I have posted a copy of the scripts I am using to draw meteograms from GFS 0.5-degree grib2 data, just like the ones at <a href="http://wxmaps.org/pix/meteograms.html" target="_blank">http://wxmaps.org/pix/meteograms.html</a>. The scripts and a brief ReadMe file are located under the directory </div>
<div> <a href="ftp://grads.iges.org/pub/jma/meteograms/" target="_blank">ftp://grads.iges.org/pub/jma/meteograms/</a></div>
<div>The scripts create a local binary subset of the data that are required to draw the meteogram. They assume that the grib2 data is local, but I think the setup would work using the GDS also, although I haven't tested it. See the ReadMe file for some additional comments. I'm sorry I don't have time to package them more neatly than this. </div>
