9/27/2023 0 Comments Multiscatter![]() If its very clear day, there's virtually no scattering. ![]() increases the adjacency effect (where signal from nearby pixels can scatter into the path collected for another pixel)Īs you might expect, the magnitude of the effects are related to the density and type of scatterers in the atmosphere.reduces the signal preferentially in the shorter wavelengths.Scattering has two primary effects on the image collected by a remote sensing instrument: In fact, once you get to about 850 nm you really don't have to worry about scattering at all. Generally speaking, they scatter the shorter wavelengths (blue-red) much more than longer ones (IR). ![]() Typical scatterers include aerosols like soot from car exhaust and smokestacks (primarily scatters red), water vapor (primarily scatters blue), or sea salts (wavelength effected depends on the type and size). The magnitude of the scattering is dependent on the size of the scatterer relative to the photon's wavelength. ISAACS and DISORT are numerical models used to simulate multiple scattering of a photon as it passes through the atmosphere. ![]()
