God, I'm going to regret opening my mouth in this echo chamber, but I'm actually curious.
It seems very reasonable to point out that lowering the temperature of the instrument, however necessary, skews the results. The cooled instrument would obviously be measuring more than back radiation. At risk of sounding like an idiot, but there's got to be some way to at least ballpark measure how much more. No?
Really? Point the uncooled instrument at the ground which according to science is radiating 350+ wm^2 and you will measure a spectrum of discrete frequencies of radiation...just turn that instrument up towards open sky which according to climate science is radiating down 330+ wm^2 and all of the spectrum of frequencies disappears...you don't get a spectrum that is less clear because of interference...you get nothing as in nothing coming in. No instrument can measure back radiation...that is radiation moving from a cooler object to a warmer object because radiation doesn't move in that direction...the second law of thermodynamics says pretty clearly that it is not possible for energy to move spontaneously from a cool object to a warmer object without some work having been done to make such movement happen.
