The Multi-angle Imaging Spectroradiometer (MISR) provides a unique opportunity for studying the ecology and climate of the Earth through the acquisition of the global multiangle imagery on the daylight side of the Earth. Viewing the sunlit Earth simultaneously at nine widely spaced angles, MISR provides radiometrically and geometrically calibrated images in four spectral bands at every angle. New algorithms for the retrieval of atmospheric aerosol, cloud, and surface geophysical properties have been implemented to capitalize on this unique observational capability.

The MISR instrument uses nine individual charge-coupled device-based pushbroom cameras to observe the Earth at nine discrete view angles: one at nadir, plus eight other symmetrical views at 26.1, 45.6, 60.0, and 70.5 degrees forward and aftward of nadir. Images at each angle are obtained in four spectral bands centered at 446, 558, 672, and 866 nm. Each band is in-flight commandable to provide sampling resolutions of 275 m, 550 m and 1.1 km.

MISR's 36 simultaneous spectral-angular images allow scientists to derive many products:

• Aerosol optical depth and particle type
• Characterization of scene type, surface albedo, and bi-directional reflectance
• Information about cloud properties
