The Multi-angle Imaging SpectroRadiometer (MISR) was successfully launched into sun-synchronous polar orbit aboard Terra, NASA's first Earth Observing System (EOS) spacecraft, on December 18, 1999. MISR measurements are designed to improve our understanding of the Earth's environment and climate. Viewing the sunlit Earth simultaneously at nine widely-spaced angles, MISR provides radiometrically and geometrically calibrated images in four spectral bands at each of the angles. Spatial sampling of 275 and 1100 meters is provided on a global basis. The MISR FAQ and Observation Concept have more details about the MISR instrument. All MISR data products are available in NetCDF-4 or HDF-EOS format.

MISR L1 and L2 Product Generation Resumes with New Data Product Format

The change in Terra orbit altitude in October 2022 required a major update to the generation of MISR L1 and L2 products because the spacecraft orbit tracks are no longer tied to a fixed set of 233 WRS-2 paths. L1 and L2 products from October 14, 2002 (orbit 121388) and later will be processed with the updates. Current orbits beginning with 126974 are now publicly available, and past orbits will become available as fill-in processing proceeds.

The MISR L1 and L2 data products are now distributed in NetCDF-4 format.

See MISR L1 and L2 Product Generation Resumes article for more detailed information.
