CALIPSO Lidar Level 2 Vertical Feature Mask data, V3-40

CAL_LID_L2_VFM_Exp-Prov-V3-40 data are CALIPSO Lidar Level 2 Vertical Feature Mask data, provisional.The Lidar Level 2 Vertical Feature Mask data 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 CAD_Score.Version 3.40 of the Level 2 data products is a maintenance release implementing the following changes.- Corrections were made to the code used to interpolate the GMAO meteorological data products to the CALIPSO orbit tracks.- The Cabannes backscattering cross-sections used to derive the molecular scattering models used for the Level 1 and Level 2 analyses were revised downward by ~0.8%.- A typographical error was identified in the runtime script that controls the behavior of the aerosol subtyping algorithm in the Level 2 analyses. Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (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 formation with five other satellites in the international A-Train (PDF) constellation for coincident Earth observations. The CALIPSO satellite comprises three instruments, the Cloud-Aerosol LIdar with Orthogonal Polarization (CALIOP), the Imaging Infrared Radiometer (IIR), and the Wide Field Camera (WFC). CALIPSO is a joint satellite mission between NASA and the French Agency, CNES.
