Sol-air temperature

From Glossary of Meteorology

sol–air temperature

The temperature that, under conditions of no direct solar radiation and no air motion, would cause the same heat transfer into a house as that caused by the interplay of all existing atmospheric conditions.

It is given by the formula
where θ is the sol–air temperature, T the outdoor air temperature, a the radiational absorptivity of the wall surface, I the incident radiation, c the coefficient of convective heat transfer between air and building material, and E the difference between the longwave radiation emitted and received by the surface. In practice, this equation has been reduced to
where θ, T, and I are the
same as above; a′ is a constant for construction material; and c′ is a constant for climate.
