[ncl-talk] Weighted vertical integral

[Adam Phillips]

Just to be clear: Following the nomenclature in the wgt_vert_avg_beta
documentation:
https://www.ncl.ucar.edu/Document/Functions/Built-in/wgt_vert_avg_beta.shtml
If you set punits = 0, then the p and psfc arrays must be in units of hPa.
If you set punits = 1, then the p and psfc arrays must be in units of Pa.

Is your punits setting consistent with the units of your passed arrays p
and psfc?

As always with ncl-talk, please respond to the email list and not to me
individually so others can see the response.
