Short summary
A TD-AMS (thermodenuder aerosol mass spectrometer) system was deployed to study the volatility of non-refractory PM1 species during winter in Shenzhen, China. The volatility of chemical species measured with the AMS varied, with nitrate showing the highest volatility. Organics showed semi-volatile characteristics, and five subtypes of OA resolved by PMF modeling presented different volatilities. The results can contribute to the understanding of the formation and ageing of submicron aerosols.
