Planetary temperature calculator

[FireAndDice]

Found this a couple days back. S'actually pretty useful.

It's a fairly streamlined little thing for determining the average surface temperature of a planet, taking into account greenhouse gases. I know I find it helpful as hell, since I don't have to fiddle around with equations. Time and effort, etc.

Sorry if this has been posted before.

Nice!

Another calculator that converts carbon dioxide partial pressure into greenhouse effect level (and that of other gases and vapours) would be nice. Earth has a low but not insignificant greenhouse effect level, while Venus' level is very high. Many worlds will be somewhere in between.
