Abstract:

Simultaneous field measurements of aerosol extinction coefficients α(λ) in the visible and IR spectral regions and the atmospheric electric field strength E are treated in the paper. Statistic correlation between α(λ) in different wavelength regions and E under conditions of atmospheric haze are analyzed. It is shown that, in the general case correlation between these parameters in realistic atmospheric hazes is insignificant. The maximum normalized correlation coefficients (~0.5) are found to occur in the visible spectral region and under conditions of increased relative air humidity. This allows the conclusion that the electric field strength in hazes is mostly influenced by fine-disperse moistened particles on which the sink of light air ions is more efficient.
