WebIncoming energy reaches the Earth from the Sun. Outgoing energy flows from Earth back out to space. "When Earth absorbs sunlight, it heats up. The heat, or "outgoing longwave radiation," radiates back into space. Satellites measure this radiation as it leaves the top of Earth's atmosphere. The hotter a place is, the more energy it radiates."
