Satellite imagery is a critical ingredient in weather forecasting. The imagery provides a thorough look at large scale weather systems and their movement. In addition, small scale features such as thunderstorms, or areas of fog, can also be detected and monitored. Two satellites provide satellite coverage over the U.S.
The sensors located on the satellites provide a variety of imagery in various resolutions and scales. This lets forecasters use satellite data to its fullest.
