ScarletRose: I believe the term is "Rayleigh Scattering". I took a college course in Geography so I should know the proper spelling, sadly when I passed the course I dumped most of the information into my mental recycle bin (you know what they say, "garbage in/garbage out", an inexact use of the term but I think it applies, LOL)
