CALIPSO Lidar Level 2 Merged Layer Diagnostic Beta, V5-00

Published by NASA/LARC/SD/ASDC | National Aeronautics and Space Administration | Catalog Last Checked: June 23, 2026 at 09:10 PM | Dataset Last Updated: June 22, 2026
CAL_LID_L2_MLay-Diagnostic-Beta-V5-00 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Lidar Level 2Merged Layer Diagnostic data product. This data product was collected using the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument. The contents of this merged layer product contain information already in the CAL_LID_L2_05kmMLay-Standard-V5-00 andCAL_LID_L2_333mMLay-Standard-V5-00 data products, but with additional diagnostic flags and parameters that were used by the science algorithms. CALIPSO was a partnership between NASA and the French Space Agency, CNES. CALIPSO was launched on April 28, 2006 to study the many roles played by clouds and aerosols in Earth’s climate and weather. It flew in the international A-Train constellation for coincident Earth observations from launch until 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 carried three remote sensing instruments: the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP), the Imaging Infrared Radiometer (IIR), and the Wide Field-of-View Camera(WFC). By mutual agreement between NASA and CNES, the CALIPSO science mission concluded on August 1, 2023.
