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 HDF-EOS format, and select products are available in netCDF format.
MISR Data and Information
The MISR Level 3 Products are global or regional maps of select parameters from the Level 2 products and associated covariances reported on various geographic grids depending on the data product. Parameters from multiple orbits are combined to make complete Level 3 global maps at daily (D), monthly (M), quarterly (Q), and yearly (Y) time scales and regional maps associated with field campaigns at daily and monthly time scales.
