Finally we choose Precomputed Atmospheric Scattering solution ( http://hal.inria.fr/inria-00288758/PDF/article.pdf)

It takes two steps:
1. use a well tested precomputed data to write the rendering part
2. write the precompute program

A new paper in GPU Pro 3 remove the pre-computation:
An Approx­i­ma­tion to the Chap­man Grazing-Incidence Func­tion for Atmos­pheric Scat­ter­ing

Qin is trying this method. Hopefully it'll be finished in 3 weeks.
