Statistical Generalization of Atmospheric Aerosol Characteristics over the White Sea (2003–2021 Expeditions)

Results are presented from a statistical generalization of data on the microphysical characteristics and ion composition of aerosols in the atmosphere of the White Sea obtained during the 2003–2021 expeditions. Based on the recalculation of the measurement results using a homogeneous data filtering algorithm, we consider the total number concentration of particles with radii of 0.2–5 μm, the volumes of fine and coarse near-water aerosol particles (smaller and larger than 0.5 μm in radius), and the volume particle distribution function. We estimate the mass concentrations of eight water-soluble ions in aerosol composition (Сa 2+ , Mg 2+ , Na + , K + , NH_4^ + , NO_3^ - , Cl – , and SO_4^2 - ) . The spatial nonuniformities and causes for anomalously high concentrations and ion composition of the aerosols are analyzed.
