How do wheather satellites work?
Question Date: 2007-03-28
Answer 1:

Depends on the satellite and what kind of data it is taking. The simplest is just a robot that orbits the Earth and has a camera that takes photographs of the clouds below it, and allows weather predictors down on Earth to look at the photographs and see what weather is coming. Some more modern satellites also have other instruments, mostly cameras that take pictures at various frequencies to get temperature, air sample, etc.
