标题： Beyond the Clouds: Advanced Data Analysis of a Dutch Sky Quality Meter Network

摘要： 光污染是一个日益严重的环境问题，对生态系统和人类健康都有影响。 本报告分析了从2020年到2023年来自washedonker.nl SQM网络的光污染数据，重点研究了间接光污染，通常称为天光。 通过整合网络中天空质量计（SQM）站的测量数据和EUMETSAT的云量数据，我们对包括荷兰北部和德国瓦登海西部地区的区域内的夜空亮度进行了全面分析。 对27个地点的亮度年度变化进行了排序和绘制图表，结果显示在最黑暗的地区，光污染每年以2.78%至6.68%的速度增加。 出现了一个趋势，即亮度较高的地区亮度变化较小，而较暗的区域变化较大。 这是由于在亮度较高的地区，人工光源如道路照明占主导地位，这减少了自然光源如月亮、星星和云层后向散射的影响。 还研究了季节性模式和银河系的影响。 密度图被用来可视化夜空亮度的变化，有助于识别光污染的具体来源，如温室照明和道路照明关闭时间。 这些发现强调了系统监测光污染的必要性，并提供了有价值的见解，可以指导公众意识活动并为光污染缓解策略提供信息。 显示英文摘要

摘要： Light pollution is an increasing environmental concern, impacting both ecological systems and human health. This report presents an analysis of light pollution data from the washetdonker.nl SQM network from 2020 until 2023, with a focus on indirect light pollution, commonly known as skyglow. By integrating measurements from Sky Quality Meter (SQM) stations in the network and cloud cover data from EUMETSAT, we conducted a comprehensive analysis of night sky brightness across a region encompassing northern Netherlands and the western part of the German Wadden Coast. Yearly changes in brightness for 27 locations were ranked and plotted, revealing that in the darkest areas, light pollution is increasing at a rate of 2.78 to 6.68 percent per year. A trend emerged showing that brighter areas experienced lower variability in brightness, while darker zones exhibited higher variability. This is due to the dominance of artificial light sources, such as street lighting, in brighter areas, which reduces the influence of natural light sources like the Moon, stars, and cloud backscatter. Seasonal patterns and the effects of the Milky Way were also investigated. Density plots were employed to visualize these changes in night sky brightness, helping to identify specific sources of light pollution, such as greenhouse lighting and streetlight turn-off times. These findings emphasize the need for systematic monitoring of light pollution and offer valuable insights that can guide public awareness initiatives and inform light pollution mitigation strategies.
