Short Name:

CALIPSO Imaging Infrared Radiometer Level 1B Radiance data, Provisional V1-11

CAL_IIR_L1-Prov-V1-11 data are Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) Infrared Imaging Radiometer Level 1B radiance data. The 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. Version 1.11 represents a transition of the Lidar, IIR, and WFC processing and browse code to a new cluster computing system. No algorithm changes were introduced and very minor changes were observed between V1.10 and V1.11 as a result of the compiler and computer architecture differences. The Level 1B data product is written in HDF. 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 the international A-Train 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.
