Growth models are much simpler calculations that calculate the change in student achievement from the beginning of the year to the end of the year.

A vast array of thought has been brought to bear on this problem, beginning with Arrhenius» simple energy balance calculation, continuing through Manabe's one - dimensional radiative - convective models in the 1960's, and culminating in today's comprehensive atmosphere - ocean general circulation models.

We used this empirically derived formula for occupancy in the PHPP «actual» internal heat gains calculation, and modelled the heating demand of a simple house across a wide range of floor areas with fixed U-values.

Some initial experimenting with a simple model of a no - atmosphere planet in synchronous orbit lead me to believe the method of calculation can make quite a difference in deltaT / deltaF.

You'll note my original comment stated chemistry was largely phenomenology «other than quantum chemistry calculations» - maybe quantum chemistry is more prevalent now than it was back when I worked in the field, but I don't believe even now it's what spectroscopists do most of the time - they make measurements and parametrize simple models, they don't work all the time from basic physical principles.

We are still talking about calculations from very simple models here, not real measurements of actual photons in the actual atmosphere over actual time (always missing from the greenhouse effect calculations — time is a fundamental component of it).

I attempted to create a simple model for calculation purposes on the skepticalscience site and even with overly conservative numbers (that favored AGW) i couldn't account for the 0.73 C increase in temperatures over the 36 year period by the reduction in OLR even using the authors» modeled results (which was between 1 - 2K reduction in OLR Brightness Temperature).
