CALIPSO Lidar Level 1B profile data, V4-10

Published by NASA/LARC/SD/ASDC | National Aeronautics and Space Administration | Metadata Last Checked: April 13, 2026 | Last Modified: 2026-04-06
CAL_LID_L1-Standard-V4-10 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Lidar Level 1B profile data, Version 4-10 data product. This data product was collected using the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument. Data collection for this product version is complete. The highest quality data products generated by the Data Management System (DMS) are referred to as Standard data products. Night and Day orbit segments are written to separate data files. A complete set of browse images, including orbit track maps, are generated and posted to the science data website. Standard data products are recommended for research studies and journal publications. The lidar Level 1B data product contains a half orbit (day or night) of calibrated and geolocated lidar profiles. The product contains data from all non-diagnostic instrument modes, including nominal science, depolarization gain ratio calibration, and boresight alignment. The lidar Level 1B product contains additional data not found in the Level 0 lidar input file, including post-processed ephemeris data, celestial data, and converted payload status data. CALIPSO was launched on April 28, 2006, and continues to collect data necessary to study the impact of clouds and aerosols on the Earth's radiation budget and climate. It flies in the international A-Train constellation for coincident Earth observations. The CALIPSO satellite comprises three instruments: CALIOP, Imaging Infrared Radiometer (IIR), and Wide Field Camera (WFC). CALIPSO is a joint satellite mission between NASA and the French Agency CNES (Centre National d'Etudes Spatiales).
