Eyes on the Earth

Eyes on the Earth (EoE) is computer visualization software created by the Jet Propulsion Laboratory (JPL) to visualize a number of NASA's Earth orbiting spacecraft in-situ and the data they collect on the Earth itself. Originally released as a Unity web player interactive, it has undergone a number of iterations including the mobile app "Earth Now".

It lets users monitor earth's vital signs, such as sea level height, atmospheric carbon dioxide concentration and Antarctic ozone. Trace the movement of water around the globe using the gravity map from NASA's GRACE satellites. Spot volcanic eruptions and forest fires using the carbon monoxide vital sign. Check out the hottest and coldest locations on Earth with the global surface temperature map.It also displays the location of all of NASA's operating Earth-observing missions in real time and lets you compare them in size to a scientist or a school bus.
