AB: The Multi-angle Imaging SpectroRadiometer (MISR) instrument provides a unique view of Earth, obtaining precisely calibrated images taken simultaneously at nine different angles and four wavelengths to produce radiance, aerosol, cloud and land surface data. MISR was launched on December 18, 1999 on the NASA Earth Observing System (EOS) Terra satellite. MISR imagery created from the Level 1 radiance data and derived quantities from the Level 2 aerosol, surface, and cloud products provide added information about natural hazards such as hurricanes, fires, floods, dust storms, and the December 2004 tsunami by exploiting both the radiometric and geometric information that are extracted from its multi-angular views. This angular perspective makes possible viewing techniques such as stereo anaglyph images and time-lapse animation to provide additional insight into characterizing these events. Better measurements can be made of parameters such as cloud height and albedo, smoke plume height, and aerosol type and height. Examples of results from MISR highlighting the value of multi-angle data will be shown. MISR data are processed, archived and distributed by the NASA Langley Atmospheric Sciences Data Center (ASDC). Data, information and tools are available at the ASDC web site, http://eosweb.larc.nasa.gov.
