Abstract

Geostationary orbit is a unique vantage point from which to view the earth and its cloud system. Since the weather moves under the satellite rather than the satellite over the weather as in lower orbits, any point within view can be observed continuously, if desired. The great distance from earth, however, imposes severe constraints on the design of the viewing sensor. Simple photometers taking advantage of the motion of spin-stabilized Applications Technology Satellites to generate one dimension of scan have demon-strated the great utility of geostationary observation for weather research and forecasting. Spin-scan sensors with vastly improved capability are now operational aboard Synchronous Meteorological Satellites; even more advanced sensors are now under development for next-generation spacecraft. This paper describes these sensors and discusses the operational requirements for which they were designed.
