2015-2024年设区市细颗粒物超标暴露人口天数积

将来源于中国环境监测总站“全国空气质量实时发布平台”和中国城市统计年鉴的原始数据，进行“年度聚合”和“人口加权”，对每日的细颗粒物污染水平和暴露在污染状况下的人口进行计算，再在全年时间尺度上进行累加，最终得出所需的暴露人口天数积数据。Raw data obtained from the National Real-time Air Quality Release Platform of the China National Environmental Monitoring Centre and the China Urban Statistical Yearbook undergoes two processing steps: annual aggregation and population weighting. Subsequently, daily fine particulate matter (PM2.5) pollution levels and the number of people exposed to such polluted conditions are computed. These daily calculated values are then accumulated over the entire annual timeframe, finally resulting in the required exposure population-day product dataset.
