Abstract
The paper presents the results of a statistical generalization of the microphysical characteristics and ionic composition of the aerosol in the atmosphere of the White Sea obtained during the expeditions of 2003-2021. Based on the recalculation of the measurement results using a uniform data filtering algorithm, the total number concentration of particles with a radius of 0.2-5 μm, the volumes of particles of fine and coarse dispersed drive aerosol with a radius of less than and more than 0.5 μm, the distribution function of particles by volume are considered, mass concentrations in the composition were estimated aerosol of eight water-soluble ions Ca2+, Mg2+, Na+, K+, NH4+, NO3-, Cl-, and SO42-. Spatial inhomogeneities and causes of anomalously high concentrations and ionic composition of the aerosol are analyzed.
