Not Mars, nor Titan. Just a logical step further from the original test 
file by Shuffle in povray.general. It is crude and would need more work 
(some latitudinal banding for instance) but that is not the point presently.

I would like to note that I use isotropic scattering (type 1) for both 
atmosphere and clouds. In the original code Shuffle used the 
Henyey-Greenstein scattering model with a slight excentricity. I think 
this use is only relevant when the camera is /inside/ the fog/cloud, 
especially the excentricity. Outside, scattering type 1 (isotropic is 
just as good and possibly faster. Think of being inside a fog bank and 
seeing the Sun poke through, or being on a mountain side and look at a 
fog bank from above.

In any case, the scene files is available in povray.general.
