Andy,<br><br> I just had a look at the RUC files on the NCEP machine and I didn't see any<br>problems. (OTOH, I didn't test all the files and you never mentioned which file<br>was causing the problem.)<br><br>
Given that you have no problems with windows, makes me suspect that you<br>
have an old wgrib2 or an ancient g2ctl.<br><br>>> <b>Warning: g2lib/g2clib jpeg deocde may differ from WMO standard, use use -g2clib 0 for WMO standardg2</b><br><br>You can ignore this error message as you are using an NCEP file. The "g2" typo indicates<br>
