The pioneer radiation balance model incorporating aerosols was Freeman and Liou (1979); for cloudiness data they cite Telegdas and London (1954).

They got 10 pages in Science, which is a lot, but in it they cover radiation balance, 1D and 3D modelling, climate sensitivity, the main feedbacks (water vapour, lapse rate, clouds, ice - and vegetation albedo); solar and volcanic forcing; the uncertainties of aerosol forcings; and ocean heat uptake.
[Response: The way the radiation is written in the Uvic model — which is typical for energy balance models of this sort — you can dial in whatever sensitivity parameter you want.
Some of the above errors in clouds compensate to provide the global mean balance in radiation required by model tuning.»
It also may impact the planet's radiation balance - largely by changing cloudiness - I have no idea whether this effect would warm or cool, that would require detailed modeling.
If the models don't reflect such differences in radiation balance between the hemispheres, then there is something wrong with the models... But globally, the oceans are warming (much) faster in the NH than in the SH...

Callendar in the 1930's (AGW a factor in early 20th warming), Plass (radiation balance) and Revelle (oceans won't absorb all anthropogenic CO2) in the 1950's, Keeling measuring CO2 in the 1960's, Manabe and others in the 1970's modelling GHG effects, etc - all contributed to the body of evidence.
When Alarmists say that ENSO's short term effects must balance to zero over the long run they are doing a priori science using the assumptions of the «radiation - only» model.
These data are used to research atmospheric radiation balance, cloud feedback processes, and to initialize and evaluate model performance, which are critical to the understanding of global climate change.
The main place this attempt at modelling breaks down, IMHO, is assessing the effect of a change in radiation balance on a change in global temperature, without feedbacks.
3) In the examination of the model for the GHE above, the initial radiation balance, plus the adiabatic - lapse rate, is what has set the structure of the temperature profile; and then the addition of more GHG to the temperature field causes a radiative imbalance that changes the temperature profile until the imbalance goes away.
Bill Gray has a favorite diagram, taken from a 1985 climate model, showing little nodules in the center with such labels as «thermal inertia» and «net energy balance» and «latent heat flux» and «subsurface heat storage» and «absorbed heat radiation» and so on, and they are emitting arrows that curve and loop in all directions, bumping into yet more jargon, like «soil moisture» and «surface roughness» and «vertical wind» and «meltwater» and «volcanoes.»
Axel Kleidon and Maik Renner of the Max Planck Institute for Biogeochemistry in Jena, Germany, used a simple energy balance model to determine how sensitive the water cycle is to an increase in surface temperature due to a stronger greenhouse effect and to an increase in solar radiation.
The change in cloud cover, neither the change in radiation balance is captured by any climate model (see Wielicki ea.
The glaciers and ice caps / sheets ECV is of importance to climate models and albedo, water balance, sea level, and radiation budget climate studies.
As of November 2014, there were 14 Earth System Models from 12 centers in eight countries that modeled temperature, soil moisture, and solar radiation at a daily resolution for at least one of the three RCPs (S1 Table)(Note: all Earth System Models that we used include feedbacks of plant production on water balance).
It is not so much the time scale of the response, just that it is not constrained or balanced by anything since we don't have convection in this radiation model.
