</font></div><div><font color="#222222" face="arial, sans-serif">Thank you for addressing this. </font></div><div><font color="#222222" face="arial, sans-serif"><br></font></div><div><font color="#222222" face="arial, sans-serif">I'm not sure if this will fix the other problem, which is that the CMC grib2 files that wrap around the globe have the international date line grid points twice (once at the western extent of the grid, and once at the eastern extent of the grid). This means that, for example, the GDPS high-res lat/lon grid (</font><a href="http://dd.weatheroffice.ec.gc.ca/model_gem_global/high_resolution/grib2/lat_lon/">http://dd.weatheroffice.ec.gc.ca/model_gem_global/high_resolution/grib2/lat_lon/</a>) has 360.6 degrees longitude. GrADS doesn't recognize this as a global dataset since it's not 360 degrees, and so it doesn't plot properly. This is occurs on the lat-lon projection data, which I'm not sure if Wesley's PS update will fix. </div>

The way I'm doing this with wgrib2 takes ~15min for the hired GDPS lat-lon grid, which is not ideal for producing forecast graphics for operational use. I'm glad that CMC is testing the compatibility of their grib2 files with GrADS. I'll re-download the latest wgrib2 and test it on the global lat-lon proj data in the next day or so.</span></div>
