Hi Greg- > Trying to calculate potential temperature from a NAM 12km grib file. Did a > search of support tickets but could not find anything. Would like to be able > to do a cross-section of potential temperature. I just did this from the NAM 12km data we have on motherlode. When you load up that dataset, you should see a Derived field for Potential Temperature under 3D grid->Temperature->Derived Note with this high resolution a dataset, the calculation is compute intensive. Is your grib file Grib 1 or 2? Does it have a pressure vertical dimension? We need that for the calculation. Are you getting an error, or do you just want to know how to do this?
