Since 2002, the Environmental Observatory of Southern Switzerland (OASI) has monitored a remarkable set of environmental parameters with the purpose of performing an enhanced observation of the regional environmental conditions. Since 2011, a campaign for the supervision of the artificial nighttime skyglow has been included in the OASI monitoring system exploiting the collaboration with DarkSky association. This network monitors the light pollution in several areas of Ticino, the southernmost Swiss Canton bordering Italy. It consists of multiple stations, which continuously measure the sky brightness. The University of Applied Sciences and Arts of Southern Switzerland, in collaboration with Politecnico di Milano, introduces the results of a study regarding the skyglow evolution during the period 2011-2016. The time-series of the OASI network were pre-processed to detect and discard data affected by natural perturbing events, such as moon and clouds presence and sun effect during twilights. In a second time, a distribution analysis of the data and an evaluation of the brightness trend during the considered period were performed. The results show that light pollution in Ticino is strictly influenced by the northern area of the nearby Italian Lombardy region and that during the surveyed years a decreasing of the pollution occurred.

自2002年以来，瑞士南部环境观测站（OASI）监测了一组引人注目的环境参数，目的是对区域环境状况进行更好的观察。自2011年以来，通过与DarkSky协会的合作，在OASI监视系统中加入了一项人工夜间夜光监管活动。该网络监视提契诺州（与意大利接壤的最南端的瑞士州）的多个地区的光污染。它由多个站点组成，可连续测量天空亮度。瑞士南部应用科学与艺术大学与米兰理工大学（Politecnico di Milano）合作，介绍了有关2011-2016年期间天窗演变的研究结果。对OASI网络的时间序列进行了预处理，以检测和丢弃受自然扰动事件影响的数据，例如，月球和云的存在以及黄昏时的太阳效应。第二次，在所考虑的时间段内对数据进行分布分析并评估亮度趋势。结果表明，提契诺州的光污染受到附近意大利伦巴第大区北部地区的严格影响，在调查的年份中，污染的发生率有所降低。
