Short summary
Hygroscopicity plays several key roles in determining aerosol optical properties and aging processes in the atmosphere. However, it is quite difficult to study aerosol hygroscopicity at the single-particle level. In this study, we built a comprehensive database linking hygroscopicities and mass spectra of individual particles. Based on the measured hygroscopicity–composition relations, we developed a statistical method to estimate ambient particle hygroscopicity just from their mass spectra.
