" In short,
W/m2 = a power figure for black bodies.
W/m2 = an energy flow figure for grey bodies. "
On second thoughts I am not sure you can have a timeless energy flow.
In fact I am pretty sure you can not.
So, for a gray body the W/m2 emitted does not reflect temperature unless corrected to a black body.
For a gray body then a W/m2 is still a power figure, BUT, amount is now more obviously missing.
Which has been my "issue" all along with the present use of W/m2, especially in K&T type plots / budgets.
Incidentally commonly titled as energy flows, which they can not be, using a power figure...
This old thread may also be of interest,
Do Global Energy budgets make sense. ???
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.
H. L. Mencken.
The hobgoblins have to be imaginary so that
"they" can offer their solutions, not THE solutions.
