Abstract

Several scaling laws have been developed relating hypothetical measurements of the scattering or extinction of the atmospheric aerosols to the scattering or extinction properties of the aerosols at other wavelengths. These scaling laws were tested in a series of numerical simulations using a number of representatives models of the atmospheric aerosols and calculations of their expected scattering and extinction properties. These simulations showed that forward scattering at fixed angles for an ultraviolet wavelength could provide useful predictions of near-IR extinction. A good correlation is also presented between forward scattering for a wavelength of 0.25 μm and backscattering at a wavelength of 1.06 μm. A comparison of 10.6-μm extinction with backscattering at 10.6 μm and extinction at a wavelength of 1.06 μm showed too much scatter to develop useful scaling laws in those case.
