Hi Darren, Without seeing the GDCROSS input I'm making a guess about how you went about this. Did you run GDVINT to interpolate to theta levels and then run this new grid file through GDCROSS? I see what you describe when I plot a linear cross-section of temperatures by the HGHT coordinate, though there are only 6 HGHT levels for TMPK in the GFS, so the scope is limited, but it does not show a surface elevation cross-section at the bottom, like you say. I'm guessing that surface elevation is only designed to show for GVCORD=PRES. I'm looking at the source code and will see if I can get it to work with height. -Michael > Good day- > I am working on putting together an isentropic analysis in GDCROSS.
