Colorimetric method for evaluation of parameters of two-leyered aerosol components of atmosphere
The question on evaluation of parameters of Atmospheric aerosols disperse components is formulated taking into account the two layered structure of former. Theoretically this task is to be settled by carrying out sun photometric measurements at two different wavelengths where absorption lines of gases are lacking. But in practice contours of continual absorption of different gases and water vapor cause significant error which make it necessary to develop new methods of analysis. Concerning the negative effect of ozone continual absorption preliminary determination of total amount of ozone is suggested. By this purpose the control measurement should be used at the wavelength 450 nm which belongs to continual Chappueu ozone absorption band. Optical depth of atmospheric aerosol at this wavelength is determined at the basis of colorimetric measurements and calculation of statistical dependence of color parameter on optical depth of aerosol at wavelength 450 nm. After calculation of total column amount of atmospheric ozone the possibility for accurate determination of turbidity parameters of aerosol disperse components is occur by carrying out sun-photometric measurements at two fixed wavelengths within Chappueu ozone absorption band.
