[gradsusr] Incorrect coordinates for WRF output in GrADS

[Ivan Toman]

Hello,

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.

I postprocess with wrfpost and then create ctl and idx with grib2ctl.pl 
and gribmap and use opengrads for display.

I'm currently unable to find why this missalignment as described above 
happen. Is it problem in GrADS, WRF, or postprocessor?

Thanks for any idea.
