Which then has its own problems for the self - sustainability model that Arsenal adopts, because if you believe some of the AST calculations, it means there's about # 30million for transfers available in the summer.

Because of the expense of doing the Venus radiative transfer calculation, there hasn't been much modelling of the Venus general circulation.

A particular emphasis of Hayward's research is on combining hydrodynamic simulations of galaxy formation with radiative transfer calculations to create «forward models» of observable quantities, such as images and spectra, that can be directly compared with data from telescopes such as the Hubble Space Telescope.

Why It Matters: Climate models involve millions of calculations on such things as air flow, heat transfer, and movement of moisture through the atmosphere.

The Coefficient 5.35 in the formula RF = 5.35 ln (CO2 / CO2 - orig) comes from basic physical principles based on radiation transfer calculations using complex models, as the note in table 6.2 so clearly shows.

A model simulation is just a series of calculations, each of which can only transfer information.

So the 3.7 W m - 2 calculation for global radiative forcing could be refined perhaps by an improved experimental design (not necessarily by improved radiative transfer models) running RT models at each grid cell over the globe, over the diurnal cycle and the annual cycle for say 30 years, for the two different CO2 concentrations, such a detailed calculation would refine the 3.7 value.

When you get to models, the radiative transfer calculations are highly parameterized and those parameterizations have been known to have been wrong in the past for some models.

TOAA is also relevant to reducing the large errors associated with numerical calculation in climate models of the transfer of heat and moisture between ocean and atmosphere.

The Wm - 2 you quote are calculations made from radiative transfer models.

You could divide up the geography into numerous cells, each with numerous layers of atmosphere; you could divide up the time into many small steps, and work out the dynamics of air masses in a refined way; you could make complex calculations of the transfer of radiation through the air; you could construct detailed models for surface effects such as evaporation and snow cover... but you could not do all these at once.
