Individual aerosol particles were directly collected with balloon-borne aerosol sampler in the free troposphere over Dunhuang, China (40.15 deg N, 94.68 deg E) on 30 August 2002 and 24 March 2003, in order to investigate detailed information about physical and chemical characteristics of aerosol particles over a source area. It was made possible to collect particles in the three different layers of 3 to 5 km, 5 to 7 km, and 7 to 9 km above sea level, by using three sets of low volume impactors each with two stages. The shape, size, and elemental composition of the collected particles were individually examined by using scanning electron microscope and energy dispersive X-ray analyzer. The absence of sulfur on the mineral particles indicated that there was no significant sulfur uptake by mineral dusts taking place in the free troposphere over the source region. In this paper, a summary and advantages of balloon-borne measurement, and characterization of individual aerosol particles based on direct collecting are presented.
