中国主要城市PM2.5浓度站点逐时监测数据（2014-2015年）

PM2.5是指大气中直径小于或等于2.5微米的颗粒物，也称为可入肺颗粒物。虽然PM2.5只是地球大气成分中含量很少的组分，但它对空气质量和能见度等有重要的影响。与较粗的大气颗粒物相比，PM2.5粒径小，富含大量的有毒、有害物质且在大气中的停留时间长、输送距离远，因而对人体健康和大气环境质量的影响更大。中国气象监测站点监测获取的PM2.5浓度数据，为大气物理、大气化学、环境遥感等相关学科领域的研究人员提供PM2.5浓度的站点监测数据。数据时间范围在2014年-2015年，包括中国大陆地区1524个站点数据。

PM2.5 refers to particulate matter with an aerodynamic diameter less than or equal to 2.5 micrometers, also known as respirable particulate matter. Although PM2.5 is only a minor component of the Earth's atmospheric composition, it exerts significant impacts on air quality, visibility and other relevant aspects. Compared with coarser atmospheric particulates, PM2.5 has smaller particle size, is rich in numerous toxic and harmful substances, and features longer residence time and longer transmission distance in the atmosphere, thus posing greater threats to human health and atmospheric environmental quality. The PM2.5 concentration data monitored by China's meteorological monitoring stations provides station-based PM2.5 concentration monitoring datasets for researchers in related disciplines such as atmospheric physics, atmospheric chemistry and environmental remote sensing. The time range of the data spans from 2014 to 2015, covering data from 1,524 monitoring stations across mainland China.
