Weather forecasters across the country and around the world rely on data provided by the NOAA Satellite and Information Service.

Every day, satellites capture images of storms and cloud cover, detect changes in the Earth's energy, measure land and sea surface temperatures, monitor precipitation, and much more.

This 24/7, uninterrupted flow of essential environmental intelligence is the backbone of the National Weather Service’s sophisticated computer modeling to create forecasts and warnings for severe weather events, thereby saving lives and protecting local communities.
