Paper Abstract

Chemical kinetic model describing the mechanism of the formation of aldehydes and the nuclei of the solid phase in the oxidation of biogenic isoprene was built on the basis of airborne measurements of aldehyde concentrations over the forests of West Siberia. It is demonstrated that the high formaldehyde concentrations at an altitude of 4 km and above are due to the photooxidation of hydrocarbons during the vertical transport from the surface. The contribution of aldehyde photonucleation into the formation of organic atmospheric aerosol is evaluated.
