摘要
大气气溶胶是地气系统的重要组成部分,是大气辐射、战场环境和气候变化等的重要影响因子之一,历来受到人们的广泛关注。为了探求气溶胶对高能激光传输时能量的衰减效应,建立气溶胶散射相函数反演算法就变得十分必要。以合肥地区为例,利用已有的商用仪器积分浊度计(TSI-3563)和太阳辐射计(PGS-100)实际测量的气溶胶散射特性和光学厚度,给出波长为0.55μm的气溶胶散射相函数的反演结果。并根据误差传递理论通过计算分析确定最终的反演误差约在12.8%。该研究将丰富气溶胶光学特性的研究手段,为相关光学工程建设提供参考。
Atmospheric aerosol is an important part of the earth-atmosphere system, and it is one of the important influence factors of radiative transfer, battlefield environment, and climate change, which has been paid more attention. In order to explore the energy attenuation effect of aerosol on high energy laser transmission, it is necessary to establish an inversion algorithm of aerosol scattering phase function. Taking Hefei region as an example, the inversion results of the wavelength of 0.55 μm aerosol scattering phase function were advanced by using the actual measurement results of aerosol scattering properties and optical thickness with the existing commercial integrating nephelometer （TSI-3563） and sunphotometer （PGS- 100）. According to the error transfer theory, the final inversion error was about 12.8%. This study will enrich the study means of aerosol optical characteristics, and provide a reference for optical engineering.
