Ice Nucleation in Arctic Cloud

Low altitude clouds are intricately linked to the Arctic’s climate and uncertainty in their interaction with aerosol means there is substantial uncertainty in projections of Arctic climate. These clouds are below 0 Degree Celsius and are therefore susceptible to the formation of ice which can dramatically alter their radiative properties, yet our knowledge of the ice nucleating particle population in …

Secondary organic aerosol reduced by mixture of atmospheric vapours

Secondary organic aerosol contributes to the atmospheric particle burden with implications for air quality and climate. Biogenic volatile organic compounds emitted from plants are important secondary organic aerosol precursors with isoprene emissions dominating globally.However, its yield of particle mass from oxidation is generally modest compared to that of other terpenoids.Herewe show that isoprene, carbon monoxide and methane can suppress the …

Recent findings on the mechanisms and atmospheric effects of new particle formation from sulfuric acid and bases

Secondary aerosol particles originating from vapors make a substantial contribution to the particle number, thus affecting the dynamics and properties of aerosol distributions, and consequently aerosol impacts on clouds and climate. This seminar discusses recent studies conducted together with e.g. University of Helsinki, Peking University and University of California, Irvine, on the very initial steps of new particle formation occurring …
