Multi-angle Imaging SpectroRadiometer

Project Description
No instrument like MISR has flown in space before. Viewing the sunlit
Earth simultaneously at nine widely spaced angles, MISR provides
ongoing global coverage with high spatial detail. Its imagery is
carefully calibrated to provide accurate measures of the brightness,
contrast, and color of reflected sunlight.

MISR provides new types of information for scientists studying Earth's
climate, such as the partitioning of energy and carbon between the
land surface and the atmosphere, and the regional and global impacts
of different types of atmospheric particles and clouds on climate. The
change in reflection at different view angles affords the means to
distinguish different types of atmospheric particles (aerosols), cloud
forms, and land surface covers. Combined with stereoscopic techniques,
this enables construction of 3-D models and estimation of the total
amount of sunlight reflected by Earth's diverse environments.
