Research Satellites for Atmospheric Sciences:  1978 – Present

http://earthobservatory.nasa.gov/Library/RemoteSensingAtmosphere/

The atmosphere changes chemically and physically on widely varying time scales—ranging from minutes to decades—and is therefore a challenge to measure precisely over the entire globe.  For 25 years, NASA and its affiliated agencies and research institutions have collaborated to develop a series of research satellites enabling scientists to advance scientific understanding of both chemical and physical changes in the atmosphere.
