You can cat grib2 files together but GrADS can only handle 1 grid definition<br>
per control file. You can use wgrib2 to convert your grib file to a common<br>
grid by<br>
<br>
wgrib2 IN.grb -new_grid_wind earth -new_grid latlon lon0:nlon:dlon<br>
lat0:nlat:dlat OUT.grb<br>
<br>
This requires that your wgrib2 was compiled with the optional IPOLATES library.<br>
