| Abstract: | The research on atmospheric aerosol in China is summarily commented in this paper,include the direct sample and analyzed, the ground and satellite remote sensing, the research of the radiative property of the atmospheric aerosols and its climate effect, the format and the transport of the dust storm. The direct sample not only analyzed the mass concentration and the size destribution, but also the chemical composition of the aerosol. The balloon observation get the aerosol's samples in the troposphere and lower stratosphere. The particles Were analyzed by using a transmission electron microscope equipped with an energh-disperive Xray analyzer. Surface remote sensind and multi satllites data, include AVHRR, SVISSR, TOMS, POLDER etc was used to retieval the radiative property of the atmospheric aerosol, special, combing the extinction and forward scattering observation and using the distribution of the sky light, the size distribution and the phase function of the aerosol are retrieval. The Climatic effect of the aerosol was research with the numerical simulation. The influence on non-spheroid particles and water soluble particles are calculated. The directed sample and analyzed of the sand paricles provide the basic knowledge used to research the formation and transport of the dust storm. Different method is discussed and several pieces of proposal are brought forward in this research area. |
