Abstract

When solving the inverse problem for the data measured with nephelometer in the visible wavelength range, the complex refractive index of aerosol particles is determined with an accuracy up to n–κ. Joint analysis of the scattering and extinction coefficients allows to obtain n and κ separately and to extend the range of particle sizes where the size distribution function is retrieved reliably. Estimates of the errors in determining n and κ, as well as the sensitivity of the measured parameters and to particles of different sizes are presented.
