<div dir="ltr">The information actually were extracted from in the namelist.wps file using WRF2GrAGS which generate the control(ctl) file.

Your model output is 640 x 460, but your descriptor file has<br>
xdef = 639 and ydef = 459. These should be 640 and 460,<br>
respectively. Also, I think what Mohsen meant was to make<br>
sure your starting lat/lon is the same in the descriptor file<br>
and model grid, i.e., you have 61.1815 as the starting lon<br>
and -3.1006 as the starting lat. Are these the same as the<br>
model grid?<br>
