CALIPSO Lidar Level 2 Vertical Feature Mask (VFM), Validated Stage 1 V3-40
CAL_LID_L2_VFM-ValStage1-V3-40 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) Lidar Level 2 Vertical Feature Mask (VFM), 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. This product describes the vertical and horizontal distribution of cloud and aerosol layers observed by the CALIPSO lidar. Cloud and aerosol discrimination for detected features is reported as a single value, the cloud-aerosol discrimination score (CAD_Score). The Version 3.40 CALIOP lidar Level 1, Level 2, and Level 3 data products incorporate the updated Global Modeling and Assimilation Office (GMAO) Forward Processing; Instrument Teams (FP-IT) meteorological data; and the enhanced Air Force Weather Authority (AFWA) Snow and Ice Data Set as ancillary inputs to the production of these data sets, beginning with data date March 1, 2013. 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.
