%X Three aerosol samplers and analyzers were used to characterize aerosol size and mass at two sites downwind of Shanghai and Beijing urban center in summer 2005. Inter-comparison was performed for the mass concentration determined by WPSTM, TEOMTM and MOUDITM. The data got from TEOM and WPS showed the correlation factor of 0.77 and 0.79. And strong correlation has been found during the hour when coarse mode particles were dominated (R=0.91 and 0.84). Also, comparison between data from WPS and MOUDI showed good correlation in difference size ranges (R ranged from 0.76 to 0.92) except the minimum stage. The particle densities at the two sites were determined based on the observed real time PM2.5 mass concentration and particle mass distribution data, respectively. The density of particles in Shanghai site was found to be around 1.70 g·cm-3 while the Beijing site had a value of 1.50 g·cm-3.
