摘要

依据全球气溶胶自动观测网在极地区域的观测

对以下问题进行了讨论:（1）温度订正在极地气溶胶光学厚度观测中的重要性及订正方法;（2）在极地进行仪器常数标定的可行性分析及温度效应的影响;（3）利用天空散射光观测反演气溶胶微物理和光学特性参数（粒子谱分布、散射相函数、复折射指数、单次散射反照率等）时

关于观测几何选择的问题

以及针对极地区域气溶胶特性的初步反演结果。这些研究可以为中国未来在两极地区开展基于自动太阳-天空辐射计的气溶胶地基遥感观测提供参考

为极地区域气溶胶卫星遥感及气候效应评估等研究提供重要支撑。

Abstract

This paper introduced several important issues on applying ground-based automatic sun-sky radiometer CE318 for aerosol remote sensing in Polar Region. Due to extremely low temperature and special weather condition like big wind in Polar R egion

scientists usually meet some particular problems when performing aerosol remote sensing based on direct sun and diffused sky light measurements. Following sun-sky radiometer CE318 measurements at polar region

this paper discussed （ 1） the importance and application of temperature correction to aerosol optical depth measurements in polar region; （ 2） temperature effects when performing instrument calibration in polar region using Langley plot method; （ 3） using diffused sky light in the retrieval of aerosol microphysical and optical properties to choose observation geometry. These studies can provide reference for performing ground-based aerosol remote sensing using automatic sun-sky radiometer in Polar Regions

and support satellite remote sensing of polar aerosol as well as assessment of its climate effects.
