Hi,Here's an FAQ, for when the locations LON, LAT, PRES represent a grid. It shows an example where the data is 2-D, but it should get you started. Note that the way the data are ordered in the file is important. If longitude varies fastest, then latitude, then pressure, this method is what you need.
