Short Name:
CAL_LID_L1-ValStage1-V3-40

CALIPSO Lidar Level 1B Profile, Validated Stage 1 V3-40

CAL_LID_L1-ValStage1-V3-40 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) Lidar Level 1B Profile, Validated Stage 1 Version 3-40 data product. Data for this product was collected using the CALIPSO Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument. Data collection for this product is ongoing. The CALIPSO lidar Level 1B data product contains a half orbit (day or night) of calibrated and geolocated single-shot (highest resolution) lidar profiles, including 532 nm and 1064 nm attenuated backscatter and depolarization ratio at 532 nm. The product released contains data from nominal science mode measurement. The CALIPSO lidar Level 1B product also contains additional data not found in the Level 0 lidar input file, including post processed ephemeris data, celestial data, and converted payload status data. The science algorithms used to produce the Version 3.40 CALIOP data products are identical to those used to generate the Version 3.01 and Version 3.02 products; however, some of the ancillary data used in the Version 3.40 analyses is different. All CALIOP data products rely on meteorological data provided by NASA's Global Modeling and Assimilation Office (GMAO). The Version 3.01 and Version 3.02 data products were produced using the GMAO's Goddard Earth Observing System Model, Version 5.2 (GEOS-5.2) data products. CALIPSO was launched on April 28, 2006 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.
