In a model perhaps...not in the real world...but feel free to show me a measurement of a discrete wavelength of radiation with an instrument that isn't cooled to a temperature lower than that of the snow drift...
The Home Depot IR thermometer is not cooled to a temperature lower than the snow pile -- YET -- it will read the surface temp of the snow pile fairly accurately...
You just REPEAT things and never learn anything.. That's why we NEED special threads for your disabilities...
I've COOLED IR detectors many times.. But NEVER to read a colder object.. They are COOLED to reduce their internal THERMAL NOISE and get better dynamic range on the the measurements.. We've been HERE twice before and you just huff it off just like all those "dogma" textbooks....
