Aug 10, 2016 · In turn, the warmed atmosphere emits longwave radiation, some of which radiates toward the Earth's surface, keeping our planet warm and generally comfortable. Increasing concentrations of greenhouse gases such as carbon dioxide and methane increase the temperature of the lower atmosphere by restricting the outward passage of emitted radiation ...
The incoming longwave radiation from the atmosphere is absorbed in the top millimeters, unlike incoming shortwave radiation that penetrates much deeper (Section 5.4.3.2). Thus, the outward longwave radiation is determined by the temperature of the literal surface or skin temperature of the sea, which is less than one millimeter thick.
Feb 19, 2022 · The difference between incoming and outgoing longwave radiation is net longwave radiation expressed as: L* = L↓ - L↑ Recall that under normal conditions air temperature decreases with an increase in altitude through the troposphere.

Outgoing longwave radiation plays an important role in planetary cooling. Longwave radiation generally spans wavelengths ranging from 3–100 microns (μm). A cutoff of 4 μm is sometimes used to differentiate sunlight from longwave radiation. Less than 1% of sunlight has wavelengths greater than 4 μm.
Incoming 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.
Earth’s climate is set by a balance between incoming solar and outgoing longwave radiation (OLR). Changes in C O 2 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?
