Abstract:

This paper presents some results obtained during two periods of measurements of the aerosol extinction coefficients carried out in the outskirts of Tomsk and in rural area during summer season. High level of the aerosol extinction has been revealed in the IR under conditions of urban haze. A physical interpretation of this fact is proposed. It is shown that the mean spectral dependence of the aerosol extinction coefficients at the wavelengths from 0.44 to 1.06 μm in a rural haze is more pronounced as compared to that in an urban haze. Strong influence of the air relative humidity on the aerosol extinction of optical radiation under background conditions is observed.
