2019年京津冀分市PM2.5浓度数据

数据为2019年京津冀分市PM2.5浓度，数据来源于中国科学院空天信息创新研究院，数据下载于生态环境部台站监测网络发布数据，用于监测京津冀地区PM2.5浓度。细颗粒物又称细粒、细颗粒、PM2.5。细颗粒物指环境空气中空气动力学当量直径小于等于 2.5 微米的颗粒物。它能较长时间悬浮于空气中，其在空气中含量浓度越高，就代表空气污染越严重。

This dataset comprises city-level PM2.5 concentration data for the Beijing-Tianjin-Hebei region in 2019. The data is sourced from the Aerospace Information Research Institute, Chinese Academy of Sciences, and was downloaded from the published data of the Ministry of Ecology and Environment station monitoring network. This dataset is intended for monitoring PM2.5 concentrations in the Beijing-Tianjin-Hebei region. Fine particulate matter, also known as fine particles or PM2.5, refers to particulate matter in ambient air with an aerodynamic equivalent diameter of 2.5 micrometers or less. It can remain suspended in the air for extended periods; the higher its concentration in the air, the more severe the air pollution.
