摘　　要：利用紫外CCD光学多道分析器,测量了云覆盖条件下的太阳紫外辐射光谱,着重研究了云对太阳紫外辐射光谱的影响。光谱分析结果表明,太阳紫外辐射光谱强度受云的影响而衰减:太阳紫外辐射光谱强度衰减依赖于波长,且随波长的递减而减小;云量越大,衰减越强;波长在315nm以下波段的太阳紫外辐射光谱强度受云影响相对较小。研究结果有较重要的实际应用价值:利用太阳紫外辐射光谱研究大气成分时,应该选择受大气环境影响较小波段的太阳光谱进行研究。In the present paper,using UV CCD optical multi-channel analyzer,the solar ultraviolet radiation spectra under the conditions of cloud cover were measured,and the impact of clouds on the solar ultraviolet radiation spectra were studied mostly.The results of spectral analysis showed that the intensity of solar ultraviolet radiation spectra was weakened by the clouds.The solar ultraviolet radiation spectral intensity attenuation depended on the wavelength and decreased with decreasing wavelength.The greater the cloud cover,the stronger the attenuation,The solar ultraviolet radiation spectral intensity at wavelengths below 315 nm was affected relatively less by the cloud cover.These results have more important practical applications.When we use solar ultraviolet radiation spectrum to study the atmospheric composition,we should choose the spectral band that is less affected by the atmospheric environment.
