Description: This diagram shows how the greenhouse effect works. Incoming solar radiation to the Earth equals 341 watts per square meter (Trenberth et al., 2009). Some of the solar radiation is reflected back from the Earth by clouds, the atmosphere, and the Earth's surface (102 watts per square meter). Some of the solar radiation passes through the atmosphere. About half of the solar radiation is absorbed by the Earth's surface (161 watts per square meter). Solar radiation is converted to heat energy, causing the emission of longwave (infrared) radiation back to the atmosphere (396 watts per square meter). Some of the infrared radiation is absorbed and re-emitted by heat-trapping "greenhouse" gases in the atmosphere. Outgoing infrared radiation from the Earth equals 239 watts per square meter.
