Tell me ian...which discrete frequencies of radiation does a Schulze-Drake radiometer measure? Do you have any idea what it measures? Sorry guy...this is just another example of you being fooled by instrumentation...take your time and learn what it actually does, before you believe what people tell you it is measuring.
Here is a clue..it is measuring the temperature changes of an internal thermopile...then applying those changes to an equation that assumes that back radiation is real...you could just as easily reconfigure it to use those temperature changes to tell you how much fairy dust is in the air...there is no back radiation...energy does not move spontaneously from cool to warm...your belief in models over reality makes you a dupe and willing to be fooled by instruments...

If only someone could prove back radiation is fake, they'd win a Nobel.....easy.
It must be hard being the only guy in the world who knows the truth.

That reminds me, energy moves from the atmosphere toward the surface, non-spontaneously (your definition), for precisely the same reason it can move non-spontaneously (your definition) from the Sun's surface toward the corona.
Love that non-spontaneous (your definition) back radiation.
