Loess, sand and coal ash samples were collected at several mineral aerosol sources to analyze the particle size as well as the major and trace elements.

A new technique using elements as a tracer for estimating relative contributions of local and non-local sources of the mineral aerosols has first been developed.

The contribution of mineral aerosol from inside Beijing to the total mineral aerosols was 30% in spring of 2002, 70% in summer of 2002,80% in autumn of 2003,20% in winter of 2002.

The rules of sand aerosol particle size distribution are found through statistical analysis.

Sand aerosol number concentration is closely related to the surface conditions, it shows aerosol number concentration is higher over desert than that of land with growing vegetables.

The rules of sand aerosol concentrations and instantaneous particle size distributions variation are found through statistical analysis.

Effect of dust aerosol production in China mainland on marine primary productivity;

Preliminary Studies on Radiative Properties of Dust Aerosol in North China;

Reason analysis of the dust aerosols’ content change in desert regions

This paper aims to make a discussion and analysis of the sand dust aerosols, their origin and their propagation and sinking process.

This paper analyzed the influences of dust aerosols on cloud properties and TOA radiative forcing in the process of the dust storm for the period of March 26 to 28,2004 over Northwest China,using data collected by MODIS(Moderate Resolution Imaging Spectroradiometer) and CERES(Clouds and the Earth s Radiant Energy Budget Scanner) instruments on the Aqua satellite.

Radiative properties and global distribution of black carbon and dust aerosols are analyzed byusing data in GADS (Global Aerosol Data Set).

On the CCN(Cloud Condensation Nuclei) condition of mineral aerosols coated with(NH4)2SO4 by heterogeneous-phase chemical processes,the rule of the condensation growth process of droplets is discussed first.
