Recently, air pollutants(fine particles, and trace gases) are key factors of the regional air quality problems and global climate change. To study the air pollutants, monitoring network developments of air pollutants provides the basic information to the analysis and application studies of air pollutants. We are monitoring air pollutants from remote sensing instruments by using solar light radiation. In addition, we develop the new observation retrieval algorithm of air pollutants including fine particles and gaseous materials for ground, airborne, and satellite sensors. Based on the original retrieval algorithm results, we analyze the long-range transport of pollutants and radiation effects for air pollutants in a regional scale.
