Abstract

The results of aerosol condensation activity obtained at the Siberian ZOTTO background station (60.8° N, 89.35° E) are presented. The measurements were carried out during the growing season from June 18 to July 6, 2021. The condensation activity of aerosol particles was estimated from cloud activation spectra measured depending on the supersaturation of water vapor and the aerosol particles size. Based on these data, the size distributions of activated particles, the critical diameters of cloud activation, and the hygroscopicity parameter of aerosol particles are calculated. The obtained cloud activation parameters are compared with similar data obtained at background stations in the Amazon rainforest and boreal forests of Northern Europe.
