How is solar energy absorbed and reflected by the earth

The atmosphere directly absorbs about 23% of incoming sunlight, and the remaining energy is transferred from the Earth’s surface by evaporation (25%), convection (5%), and thermal infrared radiation (a net of 5-6%).

7.3: Atmospheric Radiation and Earth''s Climate

Therefore, radiation is absorbed only by Earth''s surface. And the atmosphere''s emissivity is zero. That solar radiation energy, which is just the difference between the incoming solar radiation energy and the reflected solar radiation energy, equals Earth''s infrared radiation energy outgoing to

Re-radiation of heat

Solar radiation is shortwave, high-energy radiation, including visible light. When solar radiation is absorbed, it transfers its energy to Earth''s surface or atmosphere causing the temperature of the land, air, or water to increase. Because Earth is much cooler than the Sun, it re-radiates energy as longwave, lower-energy wavelengths than it

Albedo Values

Absorbed solar energy can be used to heat the surface, evaporate water, or, when sea ice or snow is present, melt the surface. A value of 1 means the surface is a "perfect reflector" that reflects all incoming energy.

What happens if solar energy is absorbed?

The absorption of solar energy heats up our planet''s surface and atmosphere and makes life on Earth possible. But the energy does not stay bound up in the Earth''s environment forever. If it did, then the Earth would be as hot as the Sun. Instead, as the rocks, the air, and the sea warm, they emit thermal radiation (heat).

Climate and Earth''s Energy Budget

About 25 percent of incoming solar energy leaves the surface through evaporation. Liquid water molecules absorb incoming solar energy, and they change phase from liquid to gas. The heat energy that it took to evaporate the water is latent in the random motions of the water vapor molecules as they spread through the atmosphere.

Albedo

Climate Change. The Earth''s climate depends on a balance of incoming and outgoing energy from the sun, which is determined by albedo. The overall albedo of the Earth - measured to be 0.30 - has a significant effect on the equilibrium temperature of the Earth as it changes how much solar energy is reflected by the Earth as opposed to how much is absorbed.

Observing Solar Energy | My NASA Data

The fraction of solar energy that is reflected to space is called the albedo. Different parts of Earth have different albedos. For example, ocean surfaces and rainforests have low albedos, which means that they reflect only a small portion of the Sun''s energy. Deserts, ice, and clouds, however, have high albedos; they reflect a large portion of
