Abstract:

Possibilities of retrieving the asymmetry factor of the atmospheric aerosol phase function from spectral measurements of light extinction and scattering are analyzed. An empirical formula for parameterization of the relation between the asymmetry factor and Ångström exponent and complex refractive index has been suggested. Several approaches to the determination of the asymmetry factor from data of integrating nephelometers are considered. An empirical relation connecting the asymmetry factor with the ratio of the scattered radiation into forward and backward hemispheres has been derived. Using the data of field measurements in Saint Petersburg suburbs in 2015, the asymmetry factor has been calculated at three wavelengths.

Keywords:

aerosol, scattering, absorption, phase function, asymmetry factor, integrating nephelometer
