Abstract

A controlled cut-off of the natural aerosol size spectrum was applied to nephelometric measurements in order to test the reliability of the retrieval of aerosol microstructure from nephelometer data. The cut-off was carried out using a 4-stage diffusion battery. It was shown that transformation of the aerosol size distribution obtained by solving the inverse problem for measured directed scattering coefficients at scattering angles of 45° and 90° and the degree of linear polarization at 90° corresponds to theoretical calculations for different stages of the diffuse battery in the particle size range from 0.07 to 0.4 μm. It was also established that inversion of the difference between the optical characteristics of non-cut and cut aerosol gives the difference between size distributions.
