DEF

Phenomenon caused by the presence of large quantities of suspended particles in the atmosphere which selectively remove the longer ... solar visible wavelengths more than the blue ... wavelengths.

CONT

Note also that the atmosphere scatters blue light much more effectively than red light. (That is why the sky appears blue.) When the sun is setting, its light passes through a lot of atmosphere. As a result, the light of the blue sun is strongly scattered and attenuated. The green sun, however, is less diminished by scattering.
