John,<br> I start to work on the .ctl file, and I have a question about the xdef and ydef. As you plotted, the left corner is not the minimal longitude and latitude of the domain. Which value should I use?<br><br>Best<br>

<div>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>

<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>
