Short summary

This study investigates the size-resolved effective density (ρ_eff) of aerosol particles in Hangzhou using a tandem aerodynamic aerosol classifier and scanning mobility particle sizer system. The ρ_eff values ranged from 1.47 to 1.63 g cm^-3, increasing with particle diameter. The relationship between ρ_eff and the particle diameter varies due to differences in the chemical composition of the particles. A new method to derive the size-resolved chemical composition of particles from ρ_eff is proposed.
