Re: calipso (hdf_eos) contour plot

Hi Lin Su,

You have Latitude and Longitude arrays on the file, but they are
dimensioned
4001 x 3, whereas Feature_Optical_Depth_532 is dimensioned 4001 x 8.

Is there some way that the Latitude/Longitude arrays are associated
with your
Feature_Optical_Depth_532 variable?
