[ncl-talk] How to get moisture flux along a boundary

[Lyndz]

> Dear Sir Dennis, NCL-experts,


I was able to calculate the moisture flux.
In the sample script, it used the  *dpres_plevel_Wrap* for the pressure
layer thickness (dp).

Is there an equivalent function for calculating *dl (length of the
boundary) *in the equation above?
