Brightness temperature calculation

    Where to find an exact formula for brightness temperature caculation?
    Only Wien's approximation is used everywhere. It is too crude for me.

    There is no exact "general" formula.
    However, the brightness can be calculated if you know the emissivity of the material (an empirical parameter, which you need look it up in a table).
