Missions & Instruments:

Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER)    This is an imaging instrument flying on NASA's Terra satellite. It is designed to obtain high-resolution global, regional and local images of Earth in 14 color bands.	Multi-angle Imaging SpectroRadiometer (MISR)    With its steeply slanting view angles, MISR is able to detect very thin plumes, such as those made of tiny particles venting from active volcanoes. MISR can also estimate the height of the plume above the surface and retrieve information about the particle size and shape if the plume floats over the dark, uniform background ocean water provides.
Shuttle Radar Topography Mission (SRTM)    SRTM created a baseline topographical map of much of the world in February 2000. Many of the world's volcanoes were measured and are now being rendered in three dimensions.
