Ivan,<div>Exactly which control file and data set are you using to plot the land/sea mask in the attached image? You said you are trying to display WRF output. The domain looks like you are running over your own domain, but you said you plotted data from the WRF NMM. This difference may cause the aberrant behavior. <div>

Hello,<br>
<br>
I have issues displaying WRF output in GrADS. The problem happens because coordinate system in GrADS (or in WRF gribs?) seems to be somehow misshaped. Attached image clearly shows example of my issue. So on the image, in color is plotted land/sea mask from WRF NMM grib file. However, on the NorthWest part of domain, and on the SouthEast part of domain, land/sea mask is tottaly out of order according to GrADS coordinating system! As you can see, Great Britain islands are moved in southwest direction almost 3 degrees, and Greece/Turkey is moved in northeast direction, and whole shape of domain is somehow deformed.<br>
<br>
I postprocess with wrfpost and then create ctl and idx with <a href="http://grib2ctl.pl" target="_blank">grib2ctl.pl</a> and gribmap and use opengrads for display.<br>
<br>
I'm currently unable to find why this missalignment as described above happen. Is it problem in GrADS, WRF, or postprocessor?<br>
<br>
Thanks for any idea.<span class="HOEnZb"><font color="#888888"><br>
