Satellite

Weather satellites are instruments in orbit around the Earth with the main goal of monitoring weather and climate.  It goes beyond just observing clouds, as sophisticated weather satellites can monitor many environmental factors like temperature, vegetation, ash and smoke clouds, ozone, ocean currents, and much more.  Satellites are either "geostationary" (in an orbit above the equator that keeps them stationary with respect to the Earth below) or "polar orbiting" (in a north to south orbit that passes over both poles of the Earth).  Geostationary satellites are about 22,300 miles above the Earth, while polar orbiting satellites are only about 530 miles above the surface (their closer range provides better resolution.
Satellites make the use of visible light to take pictures of clouds, smoke, smog, and dust which allow meteorologists to track weather systems.  They are only useful during daylight hours.  Infrared and thermal sensors allow satellites to observe ocean surface features, determine temperatures throughout the atmosphere (both over the land and ocean) and also determine the height and types of different clouds.
