The Multi-angle Imaging SpectroRadiometer, or MISR, instrument is one of five instruments aboard NASA's Terra satellite, which is collecting important data on the causes and effects of global climate change. The instrument views the Earth from nine different angles to get a better picture of various atmospheric particles, cloud forms and land surface covers.

During the Terra mission's lifetime, the Multi-angle Imaging SpectroRadiometer has been instrumental in gathering unique views of weather events such as hurricanes and floods, as well as cataloging the effects of air pollution across the globe.
