A transportable reference spectroradiometer for measuring spectral solar ultraviolet irradiance has been developed and validated. The expanded uncertainty of solar irradiance measurements with this reference spectroradiometer, based on the described methodology, is 8.8% to 4.6%, depending on the wavelength and the solar zenith angle. The accuracy of the spectroradiometer was validated by repeated site visits to two European UV monitoring sites as well as by regular comparisons with the reference spectroradiometer of the European Reference Centre for UV radiation measurements in Ispra, Italy. The spectral solar irradiance measurements of the Quality Assurance of Spectral Ultraviolet Measurements in Europe through the Development of a Transportable Unit (QASUME) spectroradiometer and these three spectroradiometers have agreed to better than 6% during the ten intercomparison campaigns held from 2002 to 2004. If the differences in irradiance scales of as much as 2% are taken into account, the agreement is of the order of 4% over the wavelength range of 300-400 nm.
一种用于测量太阳光谱紫外线辐照度的便携式参考光谱辐射计已研制成功并经过验证。基于所描述的方法，使用该参考光谱辐射计进行太阳辐照度测量的扩展不确定度为8.8%至4.6%，具体取决于波长和太阳天顶角。通过多次前往两个欧洲紫外线监测站点以及与意大利伊斯普拉的欧洲紫外线辐射测量参考中心的参考光谱辐射计定期进行比较，验证了该光谱辐射计的准确性。在2002年至2004年进行的十次比对活动中，欧洲通过开发便携式装置进行光谱紫外线测量质量保证（QASUME）光谱辐射计与这三台光谱辐射计的太阳光谱辐照度测量结果的一致性优于6%。如果考虑到辐照度标度高达2%的差异，在300 - 400 nm波长范围内，一致性约为4%。
