The hygroscopicity and volatility of submicron ambient aerosol particles with diameters of 50, 80, 110, and 150 nm and the hygroscopicity of their non-volatile cores were measured using a volatility hygroscopicity tandem differential mobility analyzer (VH-TDMA) system at a relative humidity of 90 %...
