The ISCCP group produces an independent estimate of the albedo, from performing a full
radiative flux calculation that takes into account observations of all radiative forcings and produces top of the atmosphere, surface, and in - atmosphere fluxes (data, figure right).
Not exact matches
That's far from the worst flaw in his
calculation, since his two biggest blunders are the neglect of the
radiative cooling due to sulfate aerosols (known to be a critical factor in the period in question) and his neglect of the many links in the chain of physical effects needed to translate a top of atmosphere
radiative imbalance to a change in net surface energy
flux imbalance.
(iii) Our method of
calculation for the overlap of H2O and CO2 absorption bands and our evaluation of the
radiative flux integrals are not identical with theirs.
In all
calculations of A, TA, t A, and of the
radiative flux components, the presence or absence of clouds was ignored; the
calculations refer only to the greenhouse gas components of the atmosphere registered in the radiosonde data; we call this the quasi-all-sky protocol.

The second method involves fixing the climate state at the start of the run (1850 in this case) and applying the cumulative time series for all of the forcing drivers to each year in turn, then running the
radiative calculation (only) and recording the instantaneous net
flux perturbation at the tropopause for each year in turn.
