2017年中国74主要城市大气颗粒物（PM10、PM2.5）浓度数据集

数据集包含2017年环境保护部全国城市空气质量数据，涵盖京津冀、长三角、珠三角重点城市、省会城市和计划单列市的PM10和PM2.5小时浓度数据（μg/m^3）。大气环境观测参照国家《环境空气质量标准GB3095-2012》规定的分析方法。数据集可为城市大气污染物的长期变化规律研究；模式模拟大气污染物时空分布的验证等研究提供准确的科学基础数据集。

This dataset contains national urban air quality data from the Ministry of Environmental Protection of China in 2017. It covers hourly concentration data (in μg/m³) of PM10 and PM2.5 in key cities of the Beijing-Tianjin-Hebei region, Yangtze River Delta, Pearl River Delta, provincial capital cities and cities under separate state planning. Atmospheric environmental observations are conducted in accordance with the analytical methods specified in the National Ambient Air Quality Standard GB3095-2012. This dataset can serve as an accurate scientific foundational dataset for research on long-term variation patterns of urban atmospheric pollutants, as well as for the validation of model simulations of the temporal and spatial distribution of atmospheric pollutants.
