设计了便携式太阳光度计，利用绿色L ED经光照产生电流，来研究此特定频率的光从大气外到地面上的雾霾散射效果，得到气溶胶光学厚度，实现对大气雾霾状况的检测和分析。实时测试结果表明：便携式太阳光度计可以实现气溶胶光学厚度的测试以及对大气雾霾情况的定量表征，所测数据和北京市环境监测局发布的数据规律一致。

A portable sun photometer was designed .The green LED could generate current when the light passed through it ,and the current was changed into voltage to study the haze scattering effect on this specific frequency of light from the atmosphere to the ground .Then the aerosol optical depth was obtained and the detection and analysis of the status of atmospheric haze were achieved . The test results showed that this portable sun photometer could successfully provide the quantitative characterization of the aerosol optical depth and atmospheric haze . T he trend of our measured data was almost the same as that released by the Beijing Municipal Environmental Monitoring Center .
