摘要: A thermal volatility technique was used in the boreal forest environment to examine accumulation mode (0.05-0.35 μm radius) physico-chemical properties as a function of air mass origin. Three primary aerosol species were identified all masses: (1) semi-volatile organic component, (2) ammonium sulphate, and (3) non-volatile component thought comprise mostly soot carbon. Under some conditions, sulphuric acid also identified, sea salt. Following nucleation growth new particles into sizes, fraction aerosol, by mass, observed increase from 30%, prior during event, up 75% end period, indicating substantial condensing onto newly formed particles.
