For a correct understanding and interpretation of solar UV data sampled at ground level, several practical and theoretical problems of measurement are shown. In particular, the comparison between either different sites or instruments is thoroughly analysed, and the effects due to O3 level, albedo and cloudiness are discerned. The impact of clouds and their position with respect to the sun on the observation carried out both by spectral and broad-band instruments are also examined.
为了正确理解和解释在地面采集的太阳紫外线数据，本文展示了几个测量方面的实际和理论问题。特别是，对不同地点或仪器之间的比较进行了深入分析，并识别了由于臭氧水平、反照率和云量所产生的影响。同时还研究了云层及其相对于太阳的位置对光谱仪器和宽带仪器观测结果的影响。
