NASA | Earth from Orbit 2013

A fleet of orbiting satellites monitors Earth constantly. The satellites from NASA and other space agencies give us a fresh, wide perspective on things that we can see from the ground -- and things that we can't. A look back at Earth in 2013 from the viewpoint of orbit reveals the kind of data gathering and technical achievement that are the reason NASA puts Earth-observing satellites in space. A visualization of satellite and computer model data shows how a cloud of dust from the Chelyabinsk meteor moved around the world. NASA satellites measured the intensity of wildfires, the salinity of the oceans and rainfall around the globe -- whether it was too little or too much.
