Abstract
α βλ λ τ − = ) ( a 1 where is the Angstrom exponent and is the extinction coefficient corresponding to a 1m wavelength and depends on the concentration of aerosol in the atmosphere. It is assumed that neither nor depends on the wavelength. The Angstrom is an indicator of the aerosol particle size, with smaller values of indicating large particles and larger values indicating relatively smaller aerosol particles. The Angstrom exponent is related to Junge type the particle size distribution, given as
