CALIPSO Imaging Infrared Radiometer Level 1B Radiance data, Provisional V1-13

CAL_IIR_L1-Prov-V1-13 data are Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Infrared Imaging Radiometer Level 1B radiance data, Provisional Version 1-13. The version of this product was changed from 1-12 to 1-13 to account for a change in the operating system of the CALIPSO production cluster. The Imaging Infrared Radiometer (IIR) Level 1B data product contains a half orbit of geolocated, calibrated radiances. Image data are registered to a 1 km grid centered on the lidar track. The Level 1B data product is written in HDF. 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 is comprised of three instruments, the Cloud-Aerosol LIdar with Orthogonal Polarization (CALIOP), IIR, and the Wide Field Camera (WFC). CALIPSO is a joint satellite mission between NASA and the French Agency, CNES.
