Short summary
Most pre-existing measurements lack a linkage between particle hygroscopicity and chemical composition with a high time resolution in China. Our work provided a general overview of particle hygroscopicity and its closure with chemical composition on the basis of HTDMA and AMS measurements. An increase in particle hygroscopicity with increasing air pollution level was found, as well as a quick transformation from external mixtures to internal mixtures for pre-existing particles during NPF events.
