cdiff, vertical coordinate

[Wolfgang Linder]

Hello,

if you want dt/dz but you have pressure levels
(eg: zdef 20 levels 1000 950 900 850 800 etc)
then cdiff(t,z) computes not dt/dz but dt/dp.

But since dt/dz = dt/dp * dp/dz you can
use the following:

dtdz = cdiff(t,z)/cdiff(h,z)

Best regards

Wolfgang Linder
