Earths thermal balance
WebThe global average solar radiation arriving at the outer edge of the Earth’s atmosphere is 340 watts per square metre. About seven per cent of the incoming radiation is UV radiation, 46 per cent is in the range of visible light, and the remaining 47 per cent is in the infrared spectrum. About 30 per cent of the 340 watts per square metre of ... WebFeb 1, 2024 · How is the thermal balance of the Earth maintained? The earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space. In this way, the Earth maintains a stable average temperature and therefore a stable climate. Shortwave radiation reflected to space by the earth’s …

WebCarbon dioxide forces the Earth’s energy budget out of balance by absorbing thermal infrared energy (heat) radiated by the surface. It absorbs thermal infrared energy with wavelengths in a part of the energy spectrum that other gases, such as water vapor, do not. Although water vapor is a powerful absorber of many wavelengths of thermal ... WebSep 25, 2024 · Earth’s climate is set by a balance between incoming solar and outgoing longwave radiation (OLR). Changes in CO2 or insolation perturb this balance and thus modify Earth’s climate, but exactly how does a radiative perturbation relate to changes in Earth’s surface temperature?
