[ncl-talk] CALIPSO L2 vdata

[Dennis Shea]

Please read  Example 3 at
http://www.ncl.ucar.edu/Applications/calipso.shtml

The 'altitude' is not on the file you sent. Apparently, there are ancillary
files which the user must also access to obtain the altitude data.
Example 3 shows:

CAL_LID_L2_05kmAPro-Prov-V3-01.2009-07-10T14-32-05ZD.hdf_Subset.hdf
Note the 'Subset'  partition. Please contact CALIPSO data experts. They
should be able
to clarify where these files may be found. Perhaps, also why these are not
on the original file.

Please see the HDF Dumper at
                      http://www.hdfgroup.org/hdp.html

http://www.hdfgroup.org/training/HDFtraining/UsersGuide/Utils14.html
NOTE: NCL has nothing to do with this tool. ncl-talk can not answer
questions on its usage.

*hdp dumpvd* is what you want.

Good luck
