Re: HOW TO FIND LATAND LON FROM CLOUDSAT

It looked like the HDF interface was used to convert the file to NetCDF. If you open the original file as an hdfeos file in NCL (by appending .hdfeos to the filename in the addfile call) you will likely find the SWATH lat and lon coordinates. You can use ncl_convert2nc to generate a NetCDF version using the same technique.
