CALIPSO Lidar Level 1.5 Profile, V1-01

CAL_LID_L15-Standard-V1-01 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) Lidar Level 1.5 Profile, Version 1-01 data product. Data for this product was collected using the CALIPSO Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument. The version of this product was changed from 1-00 to 1-01 to account for a change in the operating system of the CALIPSO production cluster.This product is a continuous segment of calibrated, geolocated, cloud-cleared, and spatially averaged profiles of lidar attenuated backscatter. Data collection for this product is ongoing. These profiles are derived via synthesizing the CALIPSO lidar Level 1B profile and lidar Level 2 5 km aerosol profile products with the lidar Level 2 Vertical Feature Mask (VFM) product. The lidar Level 1.5 standard data product is derived using standard Version 4.11 Level 1B and Version 4.21 Level 2 data products as input.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 (Centre National d'Etudes Spatiales).
