New Ion-Nucleation Mechanism Relevant for the Earth's Atmosphere: Experimental Data

Research output: Contribution to conferenceConference abstract for conferenceResearch

Abstract

Nucleation in the presence of ions has been studied experimentally under conditions that prevail in the lower atmosphere. In order to observe the properties of nucleation processes below 3 nm, which cannot be detected using standard techniques for measuring atmospheric aerosol, the sub 3 nm aerosols were grown via the condensation of sulphuric acid to detectable sizes. By varying the levels of ionization in the chamber differences in the resulting aerosol properties could be explored. Two types of experiments were performed: 1) A 'burst' of $H_2SO_4$ was produced from a short exposure to UV-light, and 2) steady state conditions of $H_2SO_4$ were achieved under continuous exposure to UV-light. Data obtained from both experiments will be presented.
