The suitability of a commercially available Fourier transform spectrometer equipped with a fiber-coupled global entrance optic as a reference spectroradiometer for the measurement of spectral solar ultraviolet irradiance at ground level has been investigated. The instrument has been characterized with respect to the wavelength uncertainty, and a calibration of the spectral irradiance responsivity has been performed by using the calculable irradiance of a high temperature black-body radiator and by using a secondary irradiance standard lamp. The relative standard uncertainty of solar irradiance measurements in the wavelength range from 310 nm to 400 nm with this spectroradiometer, based on the described methodology, is 1.6% for solar zenith angles of less than 60°.
已对一台配备光纤耦合整体入射光学器件的商用傅里叶变换光谱仪作为地面光谱太阳紫外辐照度测量的参考光谱辐射计的适用性进行了研究。该仪器已针对波长不确定度进行了表征，并通过使用高温黑体辐射器的可计算辐照度以及使用二级辐照度标准灯对光谱辐照度响应度进行了校准。基于所描述的方法，使用该光谱辐射计在310纳米至400纳米波长范围内进行太阳辐照度测量时，对于小于60°的太阳天顶角，相对标准不确定度为1.6%。
