The geostationary weather satellites are a critical component of the National Weather Service operations and on going nation wide modernization program. Geostationary satellites, because of their ability to constantly image the Earth, are important tools for observing severe weather such as hurricanes, severe thunderstorms, flash floods and winter storms. When satellite data are combined with other observing technologies such as weather radars, the operational forecaster has significantly increased their capabilities to produce timely, specific and very accurate short-term forecasts. The new generation of geostationary weather satellites are producing new products such as more frequent images over the United States, high density wind fields in the vicinity of hurricanes, a more comprehensive look at the phenomenon known as the Lake Effect Snow Storm, and the formation and dissipation of local fog areas. Atmospheric temperature and moisture profiles are now possible operationally with independent imager and sounder instruments. The sounder instrument is providing important information on the flow of low-level moisture from the Gulf of Mexico, an important source of energy for severe weather over the eastern part of the country.
