GOES Satellites

Geostationary Operational Environmental Satellites

 

The GOES program is a key element in NOAA's National Weather Service (NWS) operations. GOES weather imagery and quantitative sounding data are a continuous and reliable stream of environmental information used to support weather forecasting, severe storm tracking, and meteorological research. Evolutionary improvements in the geostationary satellite system since 1974 have been responsible for making the current GOES system the basic element for U. S. weather monitoring and forecasting. Spacecraft and ground-based systems work together to accomplish the GOES mission.
