Imagery and initial results from the Terra Multi-angle Imaging SpectroRadiometer (MISR)

摘要

The Multi-angle Imaging SpectroRadiometer (MISR) instrument was launched into polar orbit aboard the Terra spacecraft in December 1999, and collection of Earth imagery began in February 2000. MISR contains nine cameras pointed at fixed along-track directiosn, and acquires images with view angles at the Earth's surface ranging from 70.5 deg forward of nadir to 70.5 deg aftward. Each camera contains four CCD line arrays filtered to blue, green, red, and near-infrared wavelengths. Spatial sampling ranging from 275 m to 1.1 km is obtained over a 400-km swath width. Each area observed by MISR is imaged at all nine angles within a seven-minute period. MISR provides a unique approach to characterizing atmospheric aerosols, the surface,a nd clouds. This paper provides examples of MISR products derived from imagery acquired during the first six months of data collection.
