<P><FONT SIZE=2>Dear WRF Users:<BR>
<BR>
I am attempting to run WRF-ARW v3.1 using the ECMWF T511 Nature Run for ICs and LBCs. (Information on this dataset is available at <A HREF="http://www.emc.ncep.noaa.gov/research/JointOSSEs/data/">http://www.emc.ncep.noaa.gov/research/JointOSSEs/data/</A>). Unfortunately ungrib.exe fails with this error message:<BR>
<BR>
Originating center is 98<BR>
Grid ID is 255 Only WAFS grids 37-44 are supported<BR>
***** STOP in Subroutine RD_GRIB1.<BR>
<BR>
Based on the source code, ungrib.exe thinks this is a "thinned" WAFS grid (it uses nx=65535 as the criteria), and it clearly isn't. I don't believe anything is wrong with the GRIB data, as I can process it with PyNGL. So this looks like a bug in ungrib.exe.<BR>
<BR>
Does anyone have a solution?<BR>
