| Summary: | As an important atmospheric pollutant, the spatial and temporal variations of NO2 in the Beijing- Tianjin-Hebei (BTH) region and its influencing factors is a regional atmospheric environmental change problem that needs to be understood in depth and can provide a scientific basis for air pollution prevention and control. Using the anthropogenic emission source inventory MEIC and the environmental meteorological assessment index EMI from 2014 to 2022, this study systematically analyzes the spatiotemporal changes in anthropogenic NOx emissions and meteorological conditions during the emission reduction process in the Beijing-Tianjin-Hebei region in recent years. It quantifies the contributions of anthropogenic emissions and meteorological conditions to NO2 concentration. |
