摘要
研制了一套基于Ebert—Fastie型双光栅光谱辐射计的太阳／大气紫外光谱地基观测系统，用于获得太阳直射光谱辐照度和大气前向散射光谱辐亮度数据。详述了整套系统的结构及性能，标定了这台光谱辐射计300-400nm光谱辐照度响应度和光谱辐亮度响应度，并在长春地区（43°50’55″N，125°23’56″E）开展了太阳和大气紫外光谱辐射测量试验，获得了当地太阳和大气紫外光谱辐射数据。
Design a ground-based solar/atmosphere ultraviolet spectral radiation observation system based on an Ebert-Fastie double grating radiometer. It was used to measure solar direct spectral irradiance and atmosphere forescatter spectral radiance. The structure and performance of the system was introduced in detail. The response of spectral irradiance and spectral radiance in range from 300nm to 400nm was calibrated. Measurements of solar and atmosphere ultraviolet spectral radiation was carried out at Changchun（43°50＇55″N, 125°23＇56″E）, and the data of solar and atmosphere ultraviolet spectral radiation on sit is obtained.
