<div>hi Mike</div>

</div>
<div>first, I'd do wgrib2 -V, but suspect it has the same grib2 parameters. I'd use wgrib2 to separate the two fields into separate files...</div>

<p class="MsoNormal">Hi all,<o:p xmlns:o="#unknown"></o:p></p>
<p class="MsoNormal"><o:p xmlns:o="#unknown"> </o:p></p>
<p class="MsoNormal">I am currently dealing with an issue with GRIB2 data from The Australian BOM – They offer GRIB2 data for forecast satellite imagery. The issue though is that the 2 different satellite images both use the same variable name of BRTEMP (see
below):<o:p xmlns:o="#unknown"></o:p></p>
<p class="MsoNormal"><o:p xmlns:o="#unknown"> </o:p></p>

<p class="MsoNormal">How do I deal with this when creating a control file with g2ctl? Is this data unusable with GRADS because of this situation? If I just run g2ctl with no config, it produces a control file as follows:<br>
