Abstract: Mineral aerosol data was analysed with meteorological data of Beijing by use of multiple linear regression analysis, it indicated that there was a close relation between the monthly concentrations of mineral aerosols and the frequency of relative meteorological elements. Based on the multiple linear regression equation derived in this paper, regular meteorological data can be used to estimate the concentration of mineral aerosol. Calculated results indicated that the mineral aerosol concentrations over Beijing showed a decreasing tendency between 1971 and 1989, but this tendency slowed down during the nineties.
