The more important point is equating the kinetic energy of the atmosphere with
the upward atmospheric radiation.
Not exact matches
In the most general sense, upper
atmospheric cooling is a response to a forcing (reduction in net
upward LW + SW
radiation) that falls with height through the upper atmosphere.
Willis,» Surface
upward LW flux = 398 W / m2 Available solar
radiation = 162 W / m2 (after
atmospheric absorption and albedo reflection)»
Surface
upward LW flux = 398 W / m2 Available solar

atmospheric absorption and albedo reflection)
So we have the surprising logical conclusion that GHGs should actually facilitate
atmospheric cooling by permitting
upward radiation which could not otherwise occur.
This just says that Solar
radiation absorbed at the surface + downward
atmospheric radiation = surface
upward radiation + convection from the surface to the atmosphere.
The right side is total absorbed solar
radiation —
upward emitted
atmospheric radiation.
The partition of the outgoing long wave
radiation into
upward atmospheric emittance and surface transmitted
radiation components is based on the accurate computation of the true greenhouse - gas optical thickness for the radiosonde data.
The argument about clouds is even simpler: Clouds affect
upward and downward
radiation roughly equally, so cloud changes have negligible effect on
atmospheric temperature.
