Air Pollution Map

Air pollution became a global concern of public health and environmental govermance, especially in the developing countries. There is the need to understanding the spatio-temporal dynamics of air pollution. How to map an accurate air pollution map is the main research problem in studies of air pollution. We could explore the driver factors of air pollution based on the spatio-temmporal air pollution maps with high accuracy. We used the different methods such as spatial interpolation methods, remote sensing retrieval, machine learning and land use regression model to obatin the air pollution maps and found some interesting results. But how to intergrating the different methods is the further studies.
