I do happen to understand radiative energy transfer at a reasonable level — at least enough to understand than when the surface loses energy via radiation, its temperature drops.

6 Transfer of Energy Through Space Once the Sun's energy reaches Earth, it travels through different materials by conduction, convection, and radiEnergy Through Space Once the Sun's energy reaches Earth, it travels through different materials by conduction, convection, and radienergy reaches Earth, it travels through different materials by conduction, convection, and radiation.

Thermal energy or heat is only transferred to solids and liquids via radiation.

This is heat energy transferred by radiation, direct to us who feel the heat on our skin and absorb it deeply and feel it internally as this aka radiant heat heats up the water in us, heats our blood and flesh and bones..

I stumbled across Steve Carson's wonderfully detailed and expository blog on atmospheric radiation and energy transfer effects this morning while googling something about Grant Petty's textbook, A First Course in Atmospheric Radiation, something I've challenged myself to make a serious...

At face value it requires that no energy can be transfered via collisions, i.e. no thermal conductivity, no viscosity, no diffusion... Even for CO2, there is no mechanism for the transfer of energy from rotational / vibrational degrees of freedom to translational motion which has no coupling with a radiation field.

That claim is too simple to be useful, ignoring a) the complex interaction of Boltzmann radiation with the surface, the clouds, the GHGs, and the like, and b) the various regimes in the tropics, each of which modifies and changes the overall energy balance by things like convection and latent heat transfer.

Radiative transfer models use fundamental physical equations and observations to translate this increased downward radiation into a radiative forcing, which effectively tells us how much increased energy is reaching the Earth's surface.
