Abstract:As a part of CAREBeijing campaign, water-soluble ion mass concentration of aerosols were measured with particle-into-liquid sampler as well as the size distribution of water-soluble ion, particulate organic matter and elemental carbon measured by the MOUDI sampler. Based on these measurements, the existence patterns of each chemical species were assumed and reconstructed and then their mass concentration and number size distribution were calculated. Based on the measurements of size-resolved chemistry, relative humidity (RH), and published functional relationships between the chemical composition and water uptake, the aerosol scattering coefficients could be calculated by the Mie theory for the major particle species. The aerosol scattering hygroscopic growth factor f (RH) was then calculated. Closure study could be achieved and results from the closure study showed that the measured and the modeled values of f (RH) agree within measurement uncertainties.
