The Energy Budget

In its orbit around the Sun, the part of Earth that faces the Sun receives approximately 1,371 W/m2 of energy. Averaged over the area of Earth''s full sphere, the energy from sunlight coming to the top of the atmosphere is

BASICS IN SOLAR RADIATION AT EARTH SURFACE

The sun produces a vast amount of energy. The energy emitted by the sun is called solar energy or solar radiation. Despite the considerable distance between the sun and the earth, the amount of solar energy reaching the earth is substantial. At any one time, the earth intercepts approximately 180 106 GW. Solar radiation is the

Earth''s energy budget

OverviewEarth''s energy flowsDefinitionBudget analysisEarth''s energy imbalance (EEI)See alsoExternal links

In spite of the enormous transfers of energy into and from the Earth, it maintains a relatively constant temperature because, as a whole, there is little net gain or loss: Earth emits via atmospheric and terrestrial radiation (shifted to longer electromagnetic wavelengths) to space about the same amount of energy as it receives via solar insolation (all forms of electromagnetic radiation).

Climate and Earth''s Energy Budget

Just as the incoming and outgoing energy at the Earth''s surface must balance, the flow of energy into the atmosphere must be balanced by an equal flow of energy out of the atmosphere and back to space. Satellite measurements indicate that the atmosphere radiates thermal infrared energy equivalent to 59 percent of the incoming solar energy.

Climate and Earth''s Energy Budget

This energy plays no role in Earth''s climate system. About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.

Earth''s energy flow

The remaining 120 000 TW, or approximately 70% of the initial energy, that reaches the surface of the Earth comes down and warms the atmosphere. This portion of the pathway can be seen in Figure 2. In the atmosphere, greenhouse gas molecules absorb this thermal energy, and their temperatures rise.

Solar radiation at the Earth''s surface

Above 290 nm, the absorption of ozone becomes weaker and solar UV radiation can reach the Earth''s surface. Within the wavelength range between 285 and 310 nm, the amount of UV radiation reaching the ground is strongly dependent on the total column of ozone in the atmosphere (see Section 2.1 ).

To calculate the size of this area, the first thing we need to consider is the amount of solar radiation which actually reaches the Earth''s surface. Although the solar constant is 1,361 W/m 2, this is the intensity of the radiation which hits the top of the Earth''s atmosphere. Even on a cloudless day not all this radiation reaches the
