For realistic results, I alwasy recommend to consider reality:
In reality, the reason why the haze is only visible toward the horizon
is because the atmosphere gets less dense as you go up.
So that's exactly what I'd do with the media.
(I'd use two different media, one just for the blue with density
corresponding to atmospheric density to model some clear air, and
another one more strongly confined to lower altitudes for a white-ish
hazy air. For the blue component, Rayleigh scattering should be used
because that's what happens in the atmosphere, and for the white-ish
component one of the haze scattering modes is probbably best suited,
modelling larger dirt particles.)
