Short summary
Bioaerosols are ubiquitous in the atmosphere and may affect the cloud and precipitation formation processes. In this study, size-segregated aerosol samples were collected in boreal forest during 1 year and analysed for free amino acids, deoxyribonucleic acid, bacteria and fungi. Distinct annual patterns of bioaerosol components were observed. Also, air and soil temperature, radiation and rainfall were observed to possess a close relationship with bioaerosol abundances on an annual scale.
