Detailed Description
Top: Thermographic mosaic of Yellowstone acquired by the NASA’s MODIS-ASTER Airborne Simulator (MASTER), a thermal infrared scanner, in September 2006. Dark shades indicate cool temperatures and bright are warm; this reflects not only hydrothermal activity, but also types of ground cover. Bottom: Thermographic mosaic of a portion of Norris Geyser Basin acquired from a thermal infrared camera mounted on an aircraft, acquired in March 2015.
