- One class of thermal detectors depends on the temperature rise in the detector element caused by the absorption of infrared energy. The resulting temperature difference between detector element and surrounding heat sink is then registered by electronic means. Detectors based on this principle are called thermal detectors; they are more or less sophisticated thermometers.
The GHE was invented when in the 1960s thermal detectors reporting radiance were appearing on the market, such as the Kipp and Zonen pyrgeometers measuring temperature and reporting radiance. It can be seen as an illustration of the old fact that if you are going to lie, make it big to make it credible. To give a trace gas a big effect is a big lie.
PS The correct Planck law for one-way radiative heat transfer E between two blackbodies 1 and 2 of temperature T_1 and T_2 with T_1 bigger than T_2, is given by
- E = sigma x (T_1 - T_2) = net transfer of heat energy from 1 to 2
- E = E_1 - E_2 = net transfer of heat energy from 1 to 2
- E_1 = sigma x T_1 = gross transfer of heat energy from 1 to 2
- E_2 = sigma x T_2 = gross transfer of heat energy from 2 to 1.
If now GHE is based on an incorrect interpretation of Planck's law, the question is who is to blame? Is it Planck who formulated his law so that misinterpretation is possible? Is it the scientist who first published a misinterpretation Planck's law? If these people are no longer with us, is it a scientist who today repeats the misinterpretation printed in a book, without properly checking that what is printed by a now dead scientist is correct? Is it a scientist claiming that because it is printed in a book, it can be taken as correct? Is it the scientist responsible for the above radiance spectrum?
