Hygroscopicity is a key parameter for characterizing the ability of particles to be activated as cloud-condensation nuclei (CCN). In this study, we present a 10-month size-resolved measurement of the hygroscopicity of particles with diameters of 50, 100 and 200 nm in the Beijing urban area using a H...
