I'm not sure what's going on here: when I posted this equation (below in italics), the "e" and "s" appeared on the submitted post in Greek. I used the "& epsilon ;" and "& sigma ;" codes, but without the blanks and quotes -- when I remove the blanks they come up on the preview and submission in Greek. But when I returned to this post later, they showed up as the latin "e" and "s" characters instead. Does anyone know what is going on with rendering Greek characters in these boards?

So you would usually see the equation written as

T = [(1-a)S/(4es)]^(1/4) [the e and s were originally posted here -- and appeared -- as the Greek characters epsilon and sigma]

This equation just expresses the balance between incoming solar radiation (1-a)S/4 and outgoing emission from the Earth: esT^4 . When these quantities are equal, as they must be in radiative equilibrium, then the above relation for T is obtained.
