How To Read A Satellite Map

This is a satellite image taken by a weather satellite located 22,300 miles above the Earth. North American images are taken by the GOES (Geostationary Operational Environmental Satellite) weather satellite while other images around the world are taken by GMS5 and METEOSAT. It shows current cloud cover with the white and grey areas representing cloud cover. This map is useful in tracking the movement of storm systems, particularly where radar data is not available.

All of our satellite images offer time-lapsed loops. These loops are created by sequentially presenting satellite images of the same area over a period of a few hours. This presentation of satellite images allows a user to see the general trend of cloud movement over the past few hours. This can be especially helpful in understanding the movement of large storm systems.

Some of our satellite images are color enhanced. Located at the top of the map, a key shows how the color of cloud tops relates to how cold they are. Occasionally, the highest, coldest cloud tops produce the heaviest precipitation.
