| 摘 要： | 研制了一台可以在250 nm~400 nm波段测量绝对光谱辐亮度和绝对光谱辐照度的扫描式光谱辐射计，辐亮度辐照度相对定标准确度2％，可用于UV-A、UV-B紫外波段地基观测.通过在云南丽江地区(26°52＇N,100°13＇E)开展的大气散射光谱辐亮度和地面太阳直射紫外光谱辐照度观测试验，进一步检验了仪器的性能.观测数据与利用MODTRAN模式模拟计算值存在约8％的偏差，分析了产生偏差的相关因素.

| Abstract: | A scanning spectral radiometer which can measure absolute spectral radiance and absolute spectral irradiance from 250~400 nm was designed.The relative accuracy of radiance and irradiance calibration was 2%.The instrument was used to ground-based measurements of UV-A,UV-B ultraviolet radiation.To test performance,measurements of sky radiance and solar direct irradiance was carried out at Lijiang(26°52＇N,100°13＇E).Comparison between ground measured value and simulated value of MODTRAN model shows 8% bias.Some factors that lead to the difference were discussed. |
