whats satellite imagery?
Satellite imagery displays cloud patterns as seen from geostationary and polar orbiting satellites high above the earth’s surface. Satellite imagery is a useful tool for locating and tracking storm systems anywhere around the globe. To enable continuous night and day viewing of cloud patterns, infrared imagery is used. Infrared satellite imagery detects clouds by their temperature. The coldest clouds are displayed in bright white color, while the warmest clouds appear dark gray. In general, the coldest clouds are found at high altitudes while warmer clouds are found closer to the earth’s surface. On the enhanced satellite imagery, the coldest clouds are color coded in shades of yellow, red and purple. These areas are where the highest probability of precipitation may be found. ABOUT SATELLITE IMAGERY – satellite imagery of the earth is created from data from both geostationary and polar orbiting satellites, including: Geostationary satellites provide satellite coverage of fixed areas o
