大气气溶胶性质及其卫星遥感反演

论述了大气气溶胶的物理性质(含微物理性质)、化学性质及光学性质,特别是黑碳气溶胶的物理、化学和光学性质及其对气候强迫作用和对人居环境的影响,同时对光化学形成的二次气溶胶进行了简要介绍.指出一般气溶胶具有负气候强迫效应,而黑碳气溶胶具有较强的正气候强迫效应.在分析影响气溶胶性质的各种因素时发现,气溶胶性质除受外在环境因素影响外,也受内在的自身因素的相互影响.对卫星遥感气溶胶的原理及其在卫星遥感反演中气溶胶多种性质间复杂的相互关系进行了论述,并针对未来气溶胶的研究提出建议. 

Characteristics of Atmospheric Aerosols and Retrieval of the Satellite Remote Sensing Data

The physical properties(including microphysical properties),chemical properties and optical properties of the atmospheric aerosol are summarized,and the physical,chemical and optical properties of black carbon aerosols as well as their climate forcing effect and residential environmental effect were especially described.In addition,the secondary aerosols formed by photochemical reaction were discussed briefly.The factors influencing these aerosol properties were analyzed,and the results show that the aerosol properties could be affected by both environmental factors and inner factors existing in aerosols.In climate forcing respect,general aerosol has negative climate forcing but black carbon has positive climate forcing.Also,the principle of satellite remote sensing of aerosol and complex interrelation between these aerosol properties were discussed,and several suggestions are brought forward to accelerate the development of aerosol studies.
