well the surface produces radiation and it goes upward. I'm sure there is radiation from everything, so claiming something came for the atmosphere is slim to none. Especially if cooling is necessary to read it. so, again, cool does not flow to warm and the atmosphere is cool and the surface is warm, so same argument we've had for months and a year now. We've gone cyclical, and you still haven't proven back radiation. This does not prove it.

And the atmosphere emits radiation, which goes in all directions.

We're not discussing cool, or warm, we're discussing radiation.
What is the difference between radiation and back radiation?
it still matters.
And back radiation is IR that would be re-emitted and is coming from somewhere back from once it came. And in the atmosphere, that doesn't happen.
Oh, and if temperatures didn't apply, why does one need to cool the instrument to read?
it still matters.
All matter above 0K radiates, in all directions.
Warmer just emits more than colder
And back radiation is IR that would be re-emitted and is coming from somewhere back from once it came.
Great. We agree the ground emits. We agree the atmosphere absorbs some of the energy emitted from the ground and then emits.
And in the atmosphere, that doesn't happen.
The atmosphere doesn't emit? Why not?
Or do you mean it emits, but not toward the ground?
So why doesn't it emit toward the ground?
Oh, and if temperatures didn't apply, why does one need to cool the instrument to read?
You think the atmosphere doesn't emit toward the instrument until the instant it is cooled below a certain temp?
How does it know the temp of the instrument? Is the GHG smart? Does it have a thermometer?
Or is that the job of the photon?
