| 摘 要： | 利用紫外辐射监测资料,结合对流层紫外与可见光辐射传输模式,反演气溶胶单次散射反照率(SSA).敏感性试验和误差分析表明:紫外辐照度对SSA敏感;气溶胶光学厚度(AOD)对反演SSA的误差影响最大,波长指数次之,地表反照率和其他因素的影响较小.使用该方法计算的珠三角地区的气溶胶单次散射反照率为0.84~0.99,平均值为0.92,与以往研究相比具有较好的一致性. |

| Abstract: | The aerosol single scattering albedo (SSA) retrieved by using a ultra-violet and visible radiation transfer model (TUV) as applied to the data of broadband ultra-violet radiometer was presented in this paper. The sensitivity analysis showed that UVA was sensitive to SSA. The error of the retrieving method was mainly related to aerosol optical depth and Angstrom exponent, on the other hand, the effects of surface albedo and other factors could be neglected. The retrieved SSA in the Pearl River Delta region was about 0.84~0.99, with an average of 0.92, and agreed well with the previous studies. |
| Keywords: | aerosol single scattering albedo ultra-violet radiation radiation transfer model |
