| 摘 要： | 利用ASD地物光谱仪对杭州地区的气溶胶光学特性进行了观测并结合同步观测的太阳分光光度计CE-318的数据对其精度进行检验.分析表明,在时间演变中.杭州市冬季气溶胶光学厚度值比夏季大,气溶胶光学特性的日进程变化比较明显;从空间分异上,杭州不同区域间的差异也比较显著;杭州地区大气的浑浊度系数和波长指数主要分布在0.02～0.2和0.2～2.6之间.在气溶胶光学厚度、浑浊度系数和波长指数等大气环境重要变量中,气溶胶光学厚度和浑浊度系数之间存在正相关,而气溶胶光学厚度和波长指数之间存在负相关. |
| 关 键 词： | ASD地物光谱仪 气溶胶 气溶胶光学厚度 浑浊度系数 波长指数 |

| Abstract: | The ground-based remote sensing is one of important approach on observation of aerosol optical depth.In this study,the aerosol optical characteristics of Hangzhou region had measured using ASDspectrometer.The spatial-temporal distribution and change of aerosol optical depth,turbidity coefficient,wavelength exponent and their interrelations were analyzed,and combined with the synchronous data of Sunphotometer CE-318 made an accuracy validation.Our results indicate that the aerosol optical depth is higher in winter than in summer of Hangzhou,as well as the diurnal variation of aerosol optical characteristics is distinct obviously.The spatial patterns of aerosol optical depth are various in different region of Hangzhou.The turbidity coefficient and wavelength exponent distribute mainly from 0.02 to 0.2 and 0.2 to 2.6 respectively.The results also show that the correlation between the aerosol optical depth and turbidity coefficient is positive,while the correlation between aerosol optical depth and wavelength exponent is negative.It is a useful approaches that using ASD Spectrometer to monitor aerosol optical characteristics. |
| Keywords: | ASD spectrometer aerosol aerosol optical depth turbidity coefficient wavelength exponent |
