CALIPSO - IDL Read Package



For Your Information About the CALIPSO IDL Science Data Readers

A set of callable routines were written to provide basic read access to the CALIPSO science data files. These routines are written using Interactive Data Language (IDL) from Harris Geospatial Solutions (http://www.harrisgeospatial.com).

The routines and associated documentation are available in both tar and zipped file bundles. The documentation is provided in both Microsoft Word and PDF formats.

Questions concerning the use of these routines may be addressed to “User and Data Services” at the Atmospheric Science Data Center:
