尽管缺乏长期的记录，它是可能的，以描述许多短期的特点，依赖性和气候的表面紫外线辐照度。本文描述了智利瓦尔帕莱索（33.05°S，71.63°W，海平面）地面紫外辐照度的气候学。紫外线-B辐照度臭氧和其他气候变量的依赖关系进行了讨论，参考我们的观测在过去的四年。特别注意通过测量表面紫外线辐照度来探测“臭氧事件”。通过分析UV-B/UV-A比值的时间序列，我们抑制了云变率的影响，并检测到的事件，暗示臭氧柱的变化约15%。根据我们的测量，在过去四年中，瓦尔帕莱索上空的臭氧柱没有受到南极臭氧洞现象的负面影响。
Despite the lack of long-term records, it is possible to describe many of the short term characteristics, dependencies and climatology of surface UV irradiance. This paper describes the climatology of on ground UV irradiance at Valparaiso (33.05°S, 71.63°W, sea level), Chile. The dependence of UV-B irradiance on ozone and on other climate variables is discussed with reference to our observations conducted during the last four years. Special attention was paid to detect “ozone events” by surface UV irradiance measurements. By analyzing time series of the UV-B/UV-A ratio, we suppressed the cloud variability effect and detected events that implied ozone column changes of about 15%. According to our measurements, during the last four years, the ozone column over Valparaiso was not affected negatively by the Antarctic ozone hole phenomenon.
