<p class="MsoNormal">Hi everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m trying to display WRF data in grads but I’m hitting problems with the use of gribmap. The data are output directly by WRF in grib format, rather than through any netcdf conversion. Grib2ctl appears to work fine and gives no errors but
one of my variables appears on the same line as another in the control file initially, so I have to move it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Whenever I try and run gribmap I receive the message “gribmap error: GRIB header not found in scanning between records try increasing the value of the –s argument” I have tried increasing the value of s but to no avail. The data can be
read in fine with wgrib. Does anyone know how to fix this issue? <o:p></o:p></p>
