I remember reading some interesting facts on how long a photon stays in the atmosphere. I think Nasif Nahle posted it. What I remember was the average time a photon leaves the atmosphere is 49 hours. If the sun stopped shining it would take 80 hours for the Earth to come to -200C. Are these figures correct? Can anyone direct my back to that? I did the search but can up without. Thanks.
See my post HERE.
This has a link to one of Nasif's papers that discusses some of your query. I only have memory of a post from elsewhere that claimed if the sun didn't rise global temperature would drop below 0C in 96 hours.
Derek has links to a whole bunch of PDFs for which we need some sort of library of indexes.

If I have got what you are asking correctly, the actual time it takes for a photon emitted at the earth's surface to escape to space is 5 milliseconds.
Rate at which the earth would cool if the sun did not rise?
I am not sure, but, there is a lot of mass to cool.
On a planet of 259 trillion cubic miles !
The oceans alone, 71% of the earth's surface on average 2.5 miles deep...
AND, the earth does have a rather hot core, which most people seem to ignore....
Which is known to be releasing a lot of heat deep in the oceans.
Nasif Nahle's mean free path length of a photon,
and several of Joe Olsen's pieces are particularly worth reading,
ie, attachments to posts 1, 2 ,6, 7, and 11.

The whole aim of practical politics is to keep the populace alarmed
(and hence clamorous to be led to safety)
by menacing it with an endless series of hobgoblins, all of them imaginary.

The hobgoblins have to be imaginary so that
"they" can offer their solutions, not THE solutions.
I found it. It was an article written by Bill Illis. Perhaps on WUUT Feb, 13, 2011.
