How much solar radiation is absorbed
WebMar 2, 2024 · Solar radiation enters the atmosphere. About 18 percent of the incoming shortwave radiation is absorbed by ozone near the top of the stratosphere and in the troposphere by clouds, water vapor, and aerosols. Absorption by oxygen (O2) and ozone (O3) produces the ozone layer by the reactions: 03 + photon ^ O2 + O O3 + O ^ 2O2 WebMar 1, 1999 · The solar radiation absorbed by the Earth causes the planet to heat up until it is emitting as much energy back into space as it absorbs …
