中文摘要：

于2005年7月底至8月中旬在新疆博斯腾湖地区进行了一次野外遥感试验，其间利用法国CIMEL太阳辐射计对试验区的大气消光特性进行了测量。介绍了利用太阳辐射计对试验区气溶胶光学厚度的测量和分析原理，对测量数据进行处理研究，结果显示观测期间新疆博斯腾湖地区大气洁净，气溶胶光学厚度的日内和日间变化不大，550nm处的气溶胶光学厚度一般为0．17；Angstroem波长指数α一般为1．19，与6S常用气溶胶模式中的大陆型比较接近；大气混浊度系数β一般为0．08。

英文摘要：

From the end of July to the middle of August, 2005, a field remote sensing experiment was conducted in Bositeng Lake area, Xinjiang by Anhui Institute of Optics and Fine Mechanics, CAS. During the experiment we measured the atmospheric extinction characteristics with CIMEL sunphotometers. The method for determining atmospheric aerosol optical character from the data of CIMEL sunphotometers is described. The results show that during the experiment the aerosol optical thickness at 550 nm is about 0.17 and aerosol optical thickness variations within a day and over days are also small. Angstroem parameters and B are about 1.19 and 0.08, and comparing with the 6S typical aerosol models, the aerosol model in the area is similar to the continent model.
