摘要/Abstract

摘要： 利用太阳辐射计CE318对合肥地区大气气溶胶进行长期系统的观测，对2002年至2007年间的观测数据进行反演分析，得出了气溶胶光学厚度随时间变化的统计特征.结果表明合肥地区气溶胶光学厚度日变化有5种类型；气溶胶光学厚度随月份有波浪式变化，月平均值在4月份和8月份分别达到最大值0727和最小值0192；四季中春秋季节的气溶胶光学厚度大于夏冬季节，春季最大0636，夏季最小0262；2004年至2007年冬季气溶胶光学厚度有逐年增大的趋势.

Abstract: The atmospheric aerosols above Hefei were observed systemically and chromatically with a sun photometer CE318. The aerosol optical depth (AOD) was retrieved from the direct solar radiation data between January 2002 and December 2007, and the temporal characteristics of AOD above Hefei were analyzed. The statistic results show that there are 5 daily variation types of AOD. The AOD variation with the progression of months is wavy, reaching the maximum 0727 and the minimum 0192 in April and August respectively. The AOD in spring and summer is higher than that in summer and winter and it averages at 0636 and 0262 in Spring and Summer respectively. The AOD in winter has exhibited a steady increase from 2004 to 2007.

Key words: atmospheric optics, aerosol optical depth (AOD), Langley plot, sun photometer
