CALIPSO Imaging Infrared Radiometer (IIR) Level 1B Radiance, Standard V2-01

CAL_IIR_L1-Standard-V2-01 is the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) Imaging Infrared Radiometer (IIR) Level 1B Radiance, Standard Version 2-01 data product. Data for this product was collected using the CALIPSO IIR instrument. Data collection for this product is ongoing. 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. The Level 1B data product is written in HDF. The version of this product was changed from 2-00 to 2-01 to account for a change in the operating system of the CALIPSO production cluster.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, Cloud-Aerosol LIdar with Orthogonal Polarization (CALIOP), IIR, and Wide Field Camera (WFC). CALIPSO is a joint satellite mission between NASA and the French Agency, CNES.
