Re: How to create cross sections with netCDF files??

When sending to ncl-talk, it is best to include the output from
'printVarSummary'

 printVarSummary(air)

This will tell the ncl-talk community the 'structure' of the variable.
Otherwise people are guessing at the structure.

Of specific interest are netCDF "coordinate variables".
