<div>Hi all,</div>
<div><br>
</div>
<div>I'm trying to difference two data files, each with it's own control file, with different grid resolution. One is on a 1 X 1 degree grid and the other is 0.25 X 0.25 degrees. I understand that there is a regrid function built into grads which will map
the data from one grid to the other, however I haven't had any luck getting that function to work.</div>
<div><br>
</div>
<div>The version of grads I'm working on is Version 2.0.a1. Is the regrid function only available on later versions?</div>
<div><br>
</div>
<div>Also, does the grid resolution have to be the same in order to difference the data between the two files?</div>
<div><br>
</div>
<div>Thanks for any help you can provide.</div>
<div><br>
