Satellite Observation of Atmospheric Compositions for Air Quality and Climate Study

Atmospheric compositions, including greenhouse gases (CO2, CH4, O3, N2O), polluted trace gases (CO, NO2, and SO2), and particles (aerosol), have played important roles in impacting air quality, public health, and climate. Recent advances in remote sensing technology, especially the development of hyperspectral space-borne satellite sensors, enable us to make more accurate measurements of these species over the globe with high spatial and temporal coverage. This special issue consists of 8 articles that are involved in the study of atmospheric particles (i.e., aerosol), atmospheric trace gases (i.e., CO2, CH4, O3, N2O, and N2O), and precipitation fromsatellite observations using different sensors, such as AVHRR, IASI, GOSAT, OMI, and GOME, and model simulations. These studies include retrieval method, validation of satellite retrieval results, data analysis of spatiotemporal variation, and its relations with emissions and transport, as well as trend study.
