Level 3 globally gridded products became available in July 2002. Level 2 cloud, aerosol, and land surface products became available in February 2001. Level 1 products are available from February 24, 2000 to present. These include Level 1 raw instrument data (Level 1A); radiometrically calibrated radiances (Level 1B1); geolocated, co-registered, map-projected radiances (Level 1B2); browse data; and geometric parameters on a swath-by-swath basis. Additionally, engineering, navigation, and on-board calibrator files are also available, though these are not generally required in order to make use of Level 1 image data. Static data sets also available include the Ancillary Radiometric Product (latitudes and longitudes and surface elevations) and the Ancillary Geographic Product. All currently available data products are listed on MISR Data and Information.
