Effect of Aerosol Particles on Ozone Loss in the Tropica Stratosphere

本研究对热带平流层气溶胶粒子的数量、大小和形态特征进行了观测。球载粒子计数器表明，平流层粒子分布肯定受到活跃对流的影响。根据电子显微镜测量的粒子收集与气球携带的粒子撞击器表明，大多数particulatematter组成的硫酸液滴表明，ineat硫扩散从trophilere转化为硫酸颗粒物，如许多研究人员建议，平流层臭氧含量的垂直廓线显示了臭氧破坏的可能性在热带平流层中，大气气溶胶的非均相反应发生在臭氧低层，而在主层中则不发生.在中国、北极和南极地区，除了热带平流层气溶胶的测量外，还用新研制的粒子撞击器测量了平流层气溶胶.

In this research project number-size and morphological feature of stratosphericaerosolparticles were observed in the tropical stratosphere. The balloon-borne particle counter suggested that stratospheric particle distribution was certainly affected by active convection. According to electron microscopic measurements of the particles collected with a balloon-borne particle impactor showed that most of particulatematter were composed in sulfuric acid droplet suggesting that ineat sulfur diffused from the troposhere was converted to sulfuric acid particulate matter, as suggested by many investigators, through photochemical reactions in the stratosphere.The vertical profile of stratospheric ozone content showed the possibillity that ozone destruction through heterogeneous reaction occured in the lower ozone layr but not in tne main layr in the tropical stratosphere.The newly developed particle impactor was used in the measurements of stratospheric aerosols, in addition to the measurements of tropical stratospheric aerosols, in China, Arctic and Antarctic regions.
