Abstract. In this study we describe the hygroscopic properties of accumulation- and coarse-mode aerosol particles sampled at Zotino Tall Tower Observatory (ZOTTO) in central Siberia (61° N, 89° E) from 16 to 21 June 2013. The growth measurements were supplemented with chemical analyses samples, including inorganic ions organic/elemental carbon. addition, microstructure compositions analyzed by x-ray micro-spectroscopy (STXM-NEXAFS) transmission electron microscopy (TEM). A mass closure...

Bioparticles represent a significant fraction of the total atmospheric aerosol. Their size range varies from nanometers (macromolecules) to hundreds micrometers (plant pollen, vegetation residues) and like other aerosol particles, degree involvement bioaerosols in processes largely de- pends on their hygroscopic cloud condensation nuclei properties. In this paper ability pine, birch rape subpollen particles act as are considered. Submicron were obtained by aqueous extraction biological...
The results of back-trajectory analysis nine-year (2013–2021) measurements organic (OC) and elemental (EC) aerosol carbon concentrations made at the atmospheric monitoring station near St. Petersburg (Peterhof, 59.88° N, 29.83° E) are presented. spatial location sources was estimated by concentration weighted trajectory method (CWT) in geographic area 16°–44° E × 48°–68° N. obtained data allow us to identify territories with strongest emissions estimate seasonal variability these emissions....
The results of 5-year (20132017) measurements organic (OC) and elemental (EC) carbon aerosol fractions observed at the atmospheric monitoring station near St. Petersburg (Petergof, 59.88 N, 29.83 E) are presented. It is shown that site observations under influence local pollution sources most time (~74%). median values carbonaceous in polluted conditions 0.46 g/m3 for ЕС 2.62 ОС. On average, maximum excess EC background level achieved winter (2.4 times January). analysis ratio between OC...
