研制成太阳/大气紫外光谱辐射计,工作波段120nm至500nm,光谱分辨率0.08nm。它由标准光源,积分球,双光栅单色仪,探测器及电子学—计算机系统组成。用这台仪器进行了长春地区不同大气条件及大气质量太阳/大气紫外(260～500)nm波段光谱辐射测量。测量结果表明该仪器光谱响应稳定性好于1％/年,太阳/大气紫外波段光谱辐照度测量值(绝对值)不确定度好于3～5％。 Developed solar / atmospheric UV spectrometer, the working band 120nm to 500nm, spectral resolution 0.08nm. It consists of a standard light source, integrating sphere, dual grating monochromator, detector and electronics-computer system. The instrument was used to measure the spectral radiance of Changchun area under different atmospheric conditions and atmospheric quality of the sun / atmosphere ultraviolet (260 ~ 500) nm band. The measurement results show that the spectral response stability of the instrument is better than 1% / year, and the uncertainty of the spectral irradiance (absolute value) in the solar / atmospheric ultraviolet band is better than 3 ~ 5%.
