We developed a method for characterizing atmospheric properties from ground-based, spectral measurements of direct and scattered solar radiation under clear sky conditions. A compact spectroradiometer is employed for radiation measurement in the wavelength range between 350 and 1050 nm with a resolution of 10 nm. Spectral matching of measured and simulated spectra yields a set of optical parameters that describe optical characteristics of tropospheric aerosols. We utilize the radiative transfer code MODTRAN4 for constructing realistic atmospheric models. Details of the system calibration, analysis procedure, and the results of its performance test are described.
我们开发了一种方法，用于在晴空条件下，根据地面上对直接和散射太阳辐射的光谱测量来表征大气特性。使用一台紧凑型光谱辐射计在350至1050纳米波长范围内进行辐射测量，分辨率为10纳米。实测光谱与模拟光谱的光谱匹配产生了一组描述对流层气溶胶光学特性的光学参数。我们利用辐射传输代码MODTRAN4构建逼真的大气模型。文中描述了系统校准、分析程序及其性能测试结果的详细信息。
