The original post did not provide enough information.
ncl-talk questionq should always include something about the variables
(eg: printVarSummary). Otherwise, people are guessing at what the poster
means or the structure of the data being used. Otherwise, there are
multiple emails which are quite time consuming.
--- Some approaches: [1] Use the hydrostatic equation p = p0*exp(-g*(z-z0)/(R*T)) where z0 and p0 are the reference levels. This could be done via array notation. The results will likely have to be interpolated to constant pressure levels.
