Hi Jeff,

Excellent! This is precisely what I've been looking for. Many thanks!

If you have temperature and height data on pressure surfaces, you can calculate lapse rate as

'define lapserate = (tmpprs(z+1)-tmpprs(z-1)) / (hgtprs(z+1) - hgtprs(z-1))'

or if you're looking for the lapse rate between a specific set of pressure levels

'define dtdz75 = (tmpprs(lev=500) - tmpprs(lev=700)) / (hgtprs(lev=500) - hgtprs(lev=700))'

for instance, for the 700-500 mb layer.

Good Morning All,

Does anyone know of a way to calculate lapse rate?

I realize that lapse rate is simply the change in temperature with height but, I've been having trouble putting to the concept into a working piece of a script.
