Abstract

nderstanding the processes related to particle formation in the atmosphere is crucial in order to quantify more accurately their effect on climate. New particle formation is a global scale phenomenon, through which significant amounts of new particles are introduced in the atmosphere. A main mechanism of new particle formation is ion-induced nucleation, where vapor molecules nucleate on pre-existing atmospheric ions. It follows that in order to understand the mechanism of ion-induced nucleation, research must be focused on the very first steps of formation which normally lay in the sub-2nm size range. The work of this thesis is focused on facilitating the research on new particle formation by advancing the instrumentation state-of-the-art, but also performing experimental work on the dynamics of ion-induced nucleation.
