Abstract
Possibilities of retrieving a true value of the volume scattering coefficient and particle size distribution from data of a three-wavelength integrating nephelometer are analyzed. Two approaches to evaluation of the ratio of the true scattering coefficient to the measured one are suggested. The results of comparison of the aerosol microstructure from data of simultaneous measurements by means of integrating nephelometer and nephelometer-polarimeter PhAN are presented. The PhAN data were compared with measurements by a differential mobility analyzer.
