Abstract
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 2 5km cloud layer version 3-02 data derived from Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) Level 1B product at 5 km horizontal resolution, with full complement of diagnostic and quality assurance parameters. The data provide a range of parameters including vertical profile of cloud layers and optical depth. Version 3-30 was released in April, 2013. This version incorporates two ancillary input files updated from those used in versions 3-01 and 3-02: GEOS-5 processing system version 5.9.1 from version 5.2; and the enhanced Air Force Weather Authority (AFWA) Snow and Ice Datasets. The resulting changes are relatively small.

| Title | Deployed on Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Satellite |
| Abstract | Deployed on Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Satellite. CALIPSO is a Franco-American satellite launched in 2006, with a specific purpose of advanced measurement of cloud and aerosols. The satellite is a part of the Afternoon Constellation (A-Train) under NASA-centred Earth Observation System (EOS). A-Train is a group of polar orbiting satellites following closely with each other for synergetic measurements. They pass through the the equator around 13:00 and 01:00. CALIPSO is the first satellite that is able to provide data of vertical profiles of aerosol. These data is used for studying direct and indirect aerosol forcings. Vertical cloud profile is also required to predict precipitation and the strength of the circulation. The satellite contains Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP), Wide Field Camera (WFC) and Imaging Infrared Radiometer (IIR).
