CALIPSO Data and Information

Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) was launched on April 28, 2006 to study the roles of clouds and aerosols of climate and weather.  It flew in the international "A-Train" constellation for coincident Earth observationsuntil September 13, 2018 when CALIPSO began lowering its orbit from 705 km to 688 km (428 miles) above the Earth to resume formation flying with CloudSat as part of the “C-Train”.  The CALIPSO satellite comprises three instruments, the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP Lidar), the Imaging Infrared Radiometer (IIR), and the Wide Field Camera (WFC).  CALIPSO is a partnership between NASA and the French Space Agency, CNES.
