Исследованы сезонные распределения частиц по размерам и корреляции с коэффициентом полного рассеяния для разных аэрозольных мод. Исследована возможность аппроксимации распределений аналитическими функциями: наилучшее приближение соответствует логнормальному распределению преимущественно унимодальной формы. Проанализированы особенности сезонного хода: концентрация аэрозоля максимальна летом 2021 г. и весной 2022 г. Для указанных периодов выполнен анализ обратных траекторий движения воздушных масс с использованием модели HYSPLIT. В северных регионах источниками повышенного содержания аэрозольных частиц являются промышленные добывающие заводы. Атмосферный воздух, пришедший с восточного и юго-западного направлений, обогащен продуктами горения биомассы в результате лесных пожаров и пала травы. Показано, что аэрозольные частицы разного происхождения имеют свои значения характеристик рассеивающих свойств.</p></abstract><trans-abstract xml:lang="en"><p>The results of the analysis of the dispersed and optical characteristics of atmospheric particles according to measurements at the background station of ZOTTO tall Tower in the period of 2021–2022 are presented. Seasonal spectra of particle size distributions and correlations with the total scattering coefficient for different aerosol modes are studied. The possibility of approximating the distribution spectra by analytical functions is investigated: the best approximation corresponds to a lognormal distribution of a unimodal form predominantly. The features of the seasonal course are analyzed: the aerosol concentration has a maximum in summer of 2021 and in spring of 2022. For the specified periods, the analysis of the backward trajectories of the movement of air masses using the HYSPLIT model was performed. In the northern regions, industrial mining plants are the sources of increased aerosol particle content. The atmospheric air coming from the eastern and south-western directions is enriched with products of biomass combustion as a result of forest fires and grass fall, respectively. It is shown that the scattering properties of aerosol particles from different sources have their own characteristic values.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оптические характеристики аэрозоля</kwd><kwd>коэффициент рассеяния</kwd><kwd>нефелометр</kwd><kwd>спектрометр</kwd><kwd>HYSPLIT</kwd></kwd-group><kwd-group xml:lang="en"><kwd>optical characteristics of aerosol</kwd><kwd>scattering coefficient</kwd><kwd>nephelometer</kwd><kwd>spectrometer</kwd><kwd>HYSPLIT</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке НИР СПбГУ (№ 124032000029-9).
