Impact of land cover on air pollution at different spatial scales in the vicinity of metropolitan areas

China’s urbanization process is accompanied by land use and cover change (LUCC), influencing variations of air pollutants at multiple spatial scales. Monitoring the spatiotemporal variations of air pollutants and their relationship with land cover (LC) is vital for understanding the mechanisms of la...
