Rayleigh scattering pattern

WebHere we find new patterns in these envelopes when the scattered intensity is normalized to the Rayleigh differential cross section. Mie scattering is found to be similar to Rayleigh scattering when ρ < 1 and follows simple patterns for ρ > 1, which evolve predictably as a function of ρ. These patterns allow us to present a unifying picture ... WebMay 19, 2024 · The skylight polarization pattern of clear and pure sky is well described by the Rayleigh sky model, especially considering only the scattering of gas molecules and single scattering events. However, in the actual atmospheric scattering, there are multiple scatterings and Mei scatterings caused by clouds, dust, aerosol, and so on [ 69 – 71 ].
