Good Morning,<br><br>I am trying to use GrADS make use of some GEFS re-forecast data that is available in netCDF4 format (attached is one example, which can be accessed from: <a href="http://esrl.noaa.gov/psd/forecasts/reforecast2/download.html">http://esrl.noaa.gov/psd/forecasts/reforecast2/download.html</a>).<br>
<br>Using "sdfopen" I am successfully able to open the file.<br><br>However, only one variable is listed as available in GrADS (called "<b>inttime</b>" see below), even though ncdump indicates there is an additional variable (Pressure), which is what I originally requested from the site. <br>
<br>From GrADS:<br><br><span style="font-family:courier new,monospace">descriptor: pres_msl_latlon_all_20120101_20120101_justm8Dgdh.nc<br> Binary: pres_msl_latlon_all_20120101_20120101_justm8Dgdh.nc<br> Type = Gridded<br>
Xsize = 63 Ysize = 29 Zsize = 1 Tsize = 1 Esize = 11<br> Number of Variables = 1<br> inttime 0 t time as an integer (YYYYMMDDHH)</span><br><br>I have tried to create a data descriptor file and use xdfopen (see below)...but I can't seem to get past the 'inttime' variable. This file works if I remove the Pressure line, but again limits me to viewing the inttime variable...which is simply the date stored as an integer (2012010100). <br>
<br><span style="font-family:courier new,monospace">DSET pres_msl_latlon_all_20120301_20120301_justt-Hd8C.nc<br>TITLE This is a sample USL grid box for Central California<br>UNDEF -9999<br>XDEF lon 63 LINEAR 233.0 1.0<br>
