Incoming energy from the sun is balanced with outgoing energy from the Earth at the top of the atmosphere. This balance is maintained by clouds, the earth's surface, and the atmosphere itself.
By measuring the net radiative incoming and outgoing energy at the top of Earth's atmosphere, it is possible to determine how much energy remains in the Earth system. But where exactly does the energy go? The main energy reservoir is the ocean, which sequesters energy as heat.
At the top of the atmosphere, incoming energy from the sun is balanced with outgoing energy. This is primarily achieved by clouds reflecting energy back to space, the earth's surface radiating energy into space, and the atmosphere itself emitting energy into space.
Atmospheric energetics describe the roles of different energies in the atmospheric system. Among atmospheric energies, the mechanical energies (that is, the potential energy and the kinetic energy) are mainly related to the atmospheric movement and circulation, which influence weather and climate.
The energy balance of the Earth, and therefore the climate system, can be considered in terms of the net imbalance between absorbed shortwave radiation and outgoing longwave radiation at the top of the atmosphere.
If there was no atmosphere, energy absorption would not store as much energy near the surface. The average surface temperature of the moon, which has no atmosphere, is 0°F (-18°C). By contrast, the average surface temperature of the Earth is 59°F (15°C). This difference in temperature is due to the greenhouse effect caused by the Earth's atmosphere.
