a satellite equipped with instruments to measure and transmit data about weather features such as air pressure, humidity, and temperature. Weather satellite observations can cover high parts of the atmosphere that cannot be reached by weather balloons.
A weather satellite is a type of satellite that is primarily used to monitor the weather and climate of the Earth. These meteorological satellites, however, see more than clouds and cloud systems. City lights, fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents, energy flows, etc., are other environmental information collected from weather satellites.
