The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) was a joint-mission between NASA and the French space agency Centre National d'Etudes Spatiales. The main objectives of the mission was to supply unique data set of vertical cloud and aerosol profiles.

This dataset contains cloud and aerosol lidar level 1B version 3-01 data product, which contains processed Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) Level 0 Data and post processed ephemeris data, celestial data and converted payload status data. In version 3-01, L1B product uses enhanced daytime calibration, updated laser energy calculation algorithm, corrections to the CALIPSO orbit tracks and updated parameters.
