<b>Asunto:</b> [Wrf-users] Vtable update for new GFS data</span></p>
</div>
</div><div><div class="h5">
<p class="MsoNormal"> </p>
<p class="MsoNormal"><span lang="EN-US">The GFS data files will be updated next month probably around 17 December 2014, with changes to the filenames and the addition of 0.25-degree-resolution data. See
<a href="http://www.nws.noaa.gov/om/notification/tin14-46gfs.htm" target="_blank">http://www.nws.noaa.gov/om/notification/tin14-46gfs.htm</a> for the announcement. Most importantly for WRF users, the soil temperature representation within the grib2 file is being changed.
From the announcement:</span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Courier New";color:black" lang="EN-US">Rename TMP at 0-0.1 m, 0.1-0.4 m, 0.4-1.0 m, and 1-2 m to the</span><span style="font-size:10.5pt;font-family:Consolas;color:black" lang="EN-US">

<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">This will require a change to the Vtable.GFS file for the ungrib program to pick up the renamed fields. Based on testing of the parallel data that is currently being posted, here are the changes to the Vtable.GFS that
you need to make:</span></p>

<p class="MsoNormal"><span lang="EN-US">I’ve made a single test run with the new Vtable that appeared to complete successfully. Without this change, ungrib does not pick up the soil temperature and your WRF job may fail. Further testing by users is certainly
called for using the parallel data being posted by NCEP before the new data goes operational next month.</span></p>
