Hi Nate-

The values are in meters above sea level in the standard atmosphere.
The orginal data is probably on a pressure coordinate and in the
IDV we use the standard atmospher to convert to msl. Since it
is a straight conversion, you could also think of the vertical
axis as a pressure axis with the pressure lines being horizontal.
