  Quantum atmosphere effective radii for the emission of spin-0, -1/2, -1, and
-2 massless fields from Schwarzschild, Tangherlini, non-commutative geometry
inspired, and polymeric black holes are calculated. The power observed from the
black hole at spatial infinity taking greybody factors into account is compared
to an equal-power black-body radiator of the same temperature but different
effective radius. A large range of different radii are obtained for different
spin fields and black holes. The equal-power black-body effective radius is
not, in general, a good proxy for the location of the quantum atmosphere.
