Geostationary Satellites (Goes) Stationary with respect to a fixed point on Earth's surface (revolves at the same rate as Earth) -Far from earth (36,000 km) = coarse spatial resolution, but good temporal sampling. Visible satellite appears black where the sun is not hitting earth. See lots of black Infrared satellite shows a picture of the whole earth- also shows white around the whole earth. reads the surrounding temp of earth, so the universe is cold, shoing white. ...
