Question about brightness temperatur​e

  1. Mar 13, 2013 #1
    It is possible to convert brightness temperature of Earth surface (K) to the actual temperature?
    Is there any formulae for such conversion?
    Thanks in advance!

    I'm not sure "brightness temperature" has any meaning, but you are basically describing an infrared thermometer.

    Could this be the sort of thing you are after. Any body that is radiating energy due to its temperature alone will have a spectrum as shown in the diagram.
    I think this is used by astronomers to find the temperature of distant sources - optical and 'just warm'.
