New-particle formation involving organic compounds may play an important role in climate. Here we describe measurements at the CERN CLOUD chamber facility in which new-particle formation and growth was driven by oxidation products of alpha-pinene in the absence of inorganic species. We were able to model the growth rate of these freshly nucleated particles between 1 and 30 nm using observed distributions of highly-oxidized low-volatility organic compounds within the framework of the Volatility Basis Set. We shall discuss implications for current and pre-industrial particle formation and climate.
