中国四川盆地冬季污染期间天气强迫和云抑制对气溶胶辐射效应和边界层结构的影响数据集（2015-2021年）

四川盆地由于风小、潮湿、多云等不利气象条件，冬季持续气溶胶污染频发。基于2015-2021年的长期观测数据分析发现，四川盆地4个代表性站点经常同时出现PM2.5污染，并伴随着850hPa以上气象条件的变化，这表明四川盆地区域性冬季空气污染与大尺度的同步模式存在联系。利用T模式主成分分...Sichuan Basin experiences frequent persistent aerosol pollution in winter due to unfavorable meteorological conditions such as weak winds, high humidity, and frequent cloud cover. Based on the analysis of long-term observational data from 2015 to 2021, it is found that PM2.5 pollution frequently occurs simultaneously at four representative sites in the Sichuan Basin, accompanied by changes in meteorological conditions above 850 hPa, indicating that regional winter air pollution in the Sichuan Basin is linked to large-scale synchronous patterns.
