Abstract：The vertical profile of number concentration and size distribution of aerosol particles at different altitudes over Shijiazhuang area were analyzed based on aircraft measurements conducted in Hebei Province in 2006 and 2007. The size distributions were fitted with negative power function. The number concentration and size distribution of different heights were significantly different. The number concentration of aerosol particles in hazy days was one order of magnitude higher than that in the clean days, reaching 104 / cm3. The mean diameter of particles ranged from 0.13 to 0.26μm. Concentration of aerosol particles was very sensitive to weather conditions and the underlying surface. The size spectra of fine mode particles could be satisfactorily fitted with a negative power function.
