Abstract
A detailed study of the spatial distribution of aerosol sources is essential for understanding their impact on air quality and public health. The source fields of various atmospheric aerosol types arriving to the Middle Urals were estimated with the use of the analysis of the potential source contribution function. The initial data comprised information on the aerosol type obtained through the classification of aerosol particles based on the spectral values of atmospheric aerosol optical depth. The results demonstrate a clear spatial differentiation of atmospheric aerosol sources for the classes “dust” and “elevated smoke”. The proposed approach can significantly enhance the information provided by spectral ground-based photometric measurements, thus improving the accuracy of air quality assessments.
