CO2 molecules are incapable of absorbing any radiation above the 15 micron band from the earth's surface.

Charcoal - black world HD 149026b (illustrated here) absorbs most of the radiation it gets from its very nearby star, pushing temperatures to 3700 degrees Fahrenheit, above the boiling point of lead.
Upon exposing a metallic surface to electromagnetic radiation that is above the threshold frequency or threshold wavelength (which is specific to the type of surface and material), the photons are absorbed and current is produced.
Because the vast plateau at such altitudes absorbs a huge amount of solar radiation, the atmospheric layer above it in summer is much warmer than air at similar elevations over lower land or the oceans.
MOST HELLISH PLANET Charcoal - black world HD 149026b (illustrated here) absorbs most of the radiation it gets from its very nearby star, pushing temperatures to 3700 degrees Fahrenheit, above the boiling point of lead.
Second even if we ignore convection (and assume all warming of the atmosphere is from below, ie no incoming solar radiation is absorbed in the atmosphere) it is not the case that the atmosphere temperatures will «pivot» around some fixed level (increasing below it and falling above it).
If we are talking about clear atmosphere, then no, because the radiation will be ONLY at exactly those frequencies where the greenhouse gases above and below absorb / emit.
This skin of the skin layer would be absorbing radiation mostly emitted from layers above where the OLR is emitted.
Regions below TAU = 1 tend to have radiation absorbed before its exit to space where the opacity is high, and regions above are thin enough to let radiation escape to space.
Most UV radiation is absorbed above the tropopause, and the UV component of sunlight will varies in greater proportion with changing TSI.
All agree that direct IR radiation in the main CO2 bands is absorbed well below 1 km above the earth.
It depends on each layer receiving and absorbing radiation from above and below, and re-radiating half up and half down as heat energy, capable of raising temperature.
This energy is carried aloft by convection where the remainder of the atmosphere is essentially transparent to the emitted radiation largely because there is next to no water vapour, which is the larger absorber, in the stratosphere and above.
Then, especially when there is excessive cloud cover over the oceans, the Sun's energy absorbed above the clouds can actually make its way down to the ocean surface (and below) warming the oceans by non-radiative processes, not by direct solar radiation which mostly passes through the thin surface layer and could barely raise the mean temperature of an asphalt paved Earth above -35 C.
Misleading, inasmuch as the concept of a hot plate assumes an external heat source capable of maintaining an object sitting upon it at a constant temperature elevated above ambient, where radiation absorbed is equal to radiation emitted.
Every blackbody above 0 K is both emitting and absorbing thermal radiation
In other words, * we can observe the increase of CO2 in atmosphere above the ocean, * CO2 absorbs some part of the outgoing radiation from the surface of the ocean which increases somewhat the temperature of the air * The increasing of temperature causes the (slight) increase of the (already existing) back radiation * This (now increased) back radiation is absorbed by the surface skin layer of the ocean which means that the energy delivered by the back radiation to the surface skin layer is now slightly higher * This additional energy will now be distributed over the channels that are participating in the heat transfer from the absorbing surface skin layer to both the air above the skin layer and the bulk of the ocean.
I have claimed that, despite the 120 meter extinction, the layers above the 120 meter distance also contribute to the downwelling radiation that ultimately reaches the Surface such that, if about 1/2 are due to the first - generation photons being absorbed and re-emitted, then about 1/4, 1/8, 1/16 and so on are due to higher - generation photons due to emission and absorption, and re-emisson, and so on and on.
This absorption can even occur multiple times but once the radiation occurs high enough up in the atmosphere that the remaining IR - absorbing substances above that layer are unlikely to absorb the radiation, then it can successfully escape to space.
The heated gas molecules would bump into other air molecules and warm them, and like any material above absolute zero, the Atmosphere would emit radiation at a variety of long - wave wavelengths in random directions, some of which would be absorbed by the surface of the planet, warming it further.
So by KT97 if you let the surface be 289K as stated in TFK09 instead of 288K you can take: 67 Wm - 2 absorbed SW by the atmosphere plus 24 Wm - 2 carried upward by thermals (dry conduction / convection) plus 78 Wm - 2 carried upward by evaporation (convection) plus 66 Wm - 2 actual LW radiation flux upward (radiation)------ 235 Wm - 2 detected LW upwelling by satellites above the TOA
I say that your conclusion that CO2 absorbs most of the solar radiation above the troposphere undermines your belief in increased levels of CO2 leading to global warming.
... that your conclusion that CO2 absorbs most of the solar radiation above the troposphere undermines your belief in increased levels of CO2 leading to global warming.....
Because of the different intramolecular forces between water molecules as vapor in air, water, and ice, the wavelengths of emission and absorption are shifted; some of the radiation from the water / ice droplets at the top of a cloud can escape to space because the atmosphere above it is transparent at its wavelengths, whereas the same radiation from droplets at the bottom of a cloud will be absorbed and re-emitted in random directions from the droplets above, including back down to the originating droplets.
Back radiation of IR is already absorbed by H2O above the oceans, CO2 has no impact.
cementafriend, thanks for bring this up: «If convection occurs before radiation and the temperature of the atmosphere just above the surface is the same as the surface then it is clear that radiation to absorbing gases (CO2 and water vapour) will be zero because there is no net heat transfer between objects at the same temperature.».
I see the (nearly) black body radiation above and below those limits due to the H2O and CO2 (and other GHGs) which can (almost perfectly) absorb those wavelengths.
