Abstract:

Results of airborne measurements of aldehyde concentrations above forests of West Siberia are presented. A chemical model describing the mechanism of formation of aldehydes and solid nuclei in the course of oxidation of biogenic isoprene is constructed. It is demonstrated that the detected episodes with high (up to 9 mg/m3) formaldehyde concentration are due to the photooxidation of hydrocarbons, which act as a vertically-distributed source of aldehydes and aerosol.

Keywords:

atmospheric organic aerosol, aldehydes, photonucleation
