Abstract

Aerosols are recognized to have a role in global and regional climate and chemistry [1,2]. Sources of aerosols include mechanical generation (e.g., soil dust, sea salt spray, smoke and ash), and dispersed sources due to gas-to-particle conversion. New simultaneous measurements of ultrafine particles (i.e., having sizes from ~3–20 nm) and precursor vapor concentrations (notably H2SO4) [3–8] provides new windows into understanding natural aerosol formation processes. Nevertheless, the basic mechanisms leading to aerosol generation remain unresolved. In recent years, attention has focused on the possibility of binary homogeneous nucleation (BI-IN) of sulfuric acid and water vapor under a variety of conditions [9,10]. However, in direct applications of the classical BI-N theory [11], new particle formation is precluded in many typical situations in the lower atmosphere [3,4,12–18].
