<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">I am trying to find the maximum vertical temperature between 1000mb and 500mb in the Canadian GEM. CMC offers their variables in individual GRIB2s so, in order to get the desired profile, you have to first individually
download each level and then concatenate each of the files together to get one master temperature file.</p>
