摘要
利用 1 997～ 1 999年在西藏泽当、云南景洪观测地飞得到的大气气溶胶资料 ,分析了气溶胶粒子的物理化学特性 ,包括质量浓度、数浓度、光学吸收系数和化学组成 ,初步讨论了有关的影响因子 ,并同国内外其它地区的观测结果进行了比较。结果表明 。
Atmospheric aerosol particles were measured at Jinghong (Yunnan Province)and Zetang (Ti bet Region )meteorological observatories in the winter 1997/1998, and their physicochemical properties, such as mass concentration, size distribution, optical absorption coefficient and chemical composition, were analyzed. Results show that aerosol particles at the two sites have significant physical and chemical difference and also different from the results at other locations. Zetang has a low number density with a relative high mass concentration. This study has great practical importance to add to our knowledge of Chinese aerosol distribution and their effects on the regional climate.
