Abstract. Pollen grains emitted from vegetation can release subpollen particles (SPPs) that contribute to the fine fraction of atmospheric aerosols and may act as cloud condensation nuclei (CCN), ice (IN), or aeroallergens. Here, we investigate characterize hygroscopic growth CCN activation birch, pine, rapeseed SPPs. A high-humidity tandem differential mobility analyzer (HHTDMA) was used measure particle restructuring water uptake over a wide range relative humidity (RH) 2 % 99.5 %,...
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....
