On the Scaling of Atmospheric Aerosol Scattering and Extinction with Wavelength
Abstract
The possibility of relating the scattering or extinction by atmospheric aerosols at one wavelength to the scattering or extinction properties at another wavelength by scaling laws is examined. These scaling laws were tested using numerical simulations on representative models of the atmospheric aerosols and Mie theory calculations of their expected scattering and extinction properties. The simulations showed that forward scattering at fixed angles in the near-ultraviolet spectral region could provide useful predictions of near-infrared extinction. A good correlation is also presented between calculated forward scattering for a wavelength of 0.25 micrometers and backscattering at a wavelength of 1.06 micrometers. In comparison of the 10.6 micrometers extinction with backscattering at 10.6 micrometers and with extinction at a wavelength of 1.06 micrometers, both showed too much scatter to develop useful scaling laws in those cases.
