WebIncoming energy reaches the Earth from the Sun. Outgoing energy flows from Earth back out to space. "When Earth absorbs sunlight, it heats up. The heat, or "outgoing longwave radiation," radiates back into space. Satellites measure this radiation as it leaves the top of Earth's atmosphere. The hotter a place is, the more energy it radiates." WebYet something puzzling happens: While one would expect the longwave radiation that escapes into space to decline with increasing CO 2, the amount actually begins to rise. At the same time, the atmosphere absorbs more and more incoming solar radiation; it’s this enhanced shortwave absorption that ultimately sustains global warming.

WebDec 11, 2024 · Outgoing radiation from the Earth's surface (or its atmosphere) are being emitted by a much cooler body than the Sun. There is a strong reciprocal relationship (a one-to-one relationship in the case of a blackbody) between the temperature of the emitter and the inverse of the wavelength peak of its emission spectrum. WebApr 15, 2024 · where α is the surface albedo, R s ↓ is the incoming shortwave radiation (W/m 2), R l ↓ is the incoming longwave radiation (W/m 2), R l ↑ is the outgoing longwave radiation (W/m 2), and ε g is the land surface emissivity.
