Convection is based on the VERY near surface temperature whereas SB is based on the temperature of the larger air mass
in radiative exchange with the surface.
Since the Lapse Rate for the atmosphere is around 6.5 DegC / Km, air higher in the atmosphere
in radiative exchange with the ground will be at varying temperatures.

The recent JCAP paper published
in Nature Communications introduces a transcendent approach to understanding PEC device performance for arbitrary material and device quality, using five representative parameters: semiconductor absorption fraction, external
radiative efficiency, series resistance, shunt resistance and catalytic
exchange current density to account for imperfect light absorption, charge transport and catalysis.
ENSO events, for example, can warm or cool ocean surface temperatures through
exchange of heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the
radiative balance
in the lower atmosphere).

I didn't know that data since 1850 as summarized is essentially useless for estimating climate sensitivity given that the Earth's
radiative heat
exchange is not
in equilibrium over that period.
To obtain realistic simulations, it was found necessary to include additional energy sources and sinks:
in particular, energy
exchanges with the surface and moist atmospheric processes with the attendant latent heat release and
radiative heat inputs.
For those who want to check out the physics, read up the statistical thermodynamics which leads to Kirchhoff; s law of radiation and realise that «Prevost
exchange energy» is needed to connect the IR density of states
in the two objects
in radiative equilibrium and maintain absorptivity = emissivity.
However, the second law is not violated by the greenhouse effect, of course, since, during the
radiative exchange,
in both directions the net energy flows from the warmth to the cold.»
i) The total
exchange of radiation between Space and the TOA and between surface and the TOA is sufficiently large that an increase
in the
radiative capabilities of an atmospheric constituent that amounts to 0.04 % of the atmosphere would appear unlikely to have any significant effect.
Given the vast pool of very cold water
in the deep ocean, even modest changes
in the rate it
exchanges heat with the surface can produce large changes
in temperature without any change
in the planetary
radiative balance.
Vis.: www.garfield.library.upenn.edu/classics1981/A1981LQ21800001.pdf Even more to the point, he goes on to state that [quote] «The regions of validity of the linear, square root, and nonoverlapping approximations were considered
in this article...» [endquote] and notes that the summary of the [quote] «various models and approximations for band absorption» [endquote] given
in that article had apparently been useful
in many later studies requiring [quote] «mathematical calculation» [endquote] of the
radiative exchange by infrared bands.
The rationales for coupling are to investigate potentially significant feedbacks (e.g.,
radiative properties for different airborne crystalline ice structures, changes
in air and water inertia due to suspended dust and sediments, and water and other material
exchanges with plants and biome evolution) and to achieve ever fuller depictions of Earth's fluid envelope.
Lateral expansion and carbon
exchange of a boreal peatland
in Finland resulting
in 7000 years of positive
radiative forcing.
But simple
radiative exchange between two ideal bodies
in a vacuum is very basic and very comprehensible.
However, six out of the 19 references
in the paper are to Miskolczi himself and the fundamental equations brought up for energy balance (where
radiative exchange is referenced) rely on his more lengthy 2007 paper, Greenhouse effect
in semi-transparent planetary atmospheres.
There is more
in the paper, including some very suspect assumptions about
radiative exchange.
This and my previous posting
in this series address ONLY the
radiative exchange of energy.
When discussing
radiative thermal energy
exchange between two objects, it may very well be more appropriate to talk about the heat between objects and not mention the rate thermal energy leaves each object
in the direction of the other object.
That the Green House Effect works by
radiative exchanges in an atmospheric column of decreasing temperatures should also be common knowledge.
