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, andSO2), and particles (aerosol), have played important rolesin impacting air quality, public health, and climate. Recentadvances in remote sensing technology, especially the developmentof hyperspectral space-borne satellite sensors, enableus to make more accurate measurements of these species overthe globe with high spatial and temporal coverage.This special issue consists of 8 articles that are involved inthe study of atmospheric particles (i.e., aerosol), atmospherictrace gases (i.e., CO2, CH4, O3, N2O, and N2O), and precipitationfromsatellite observations using different sensors, suchas AVHRR, IASI, GOSAT, OMI, and GOME, and model simulations.These studies include retrieval method, validationof satellite retrieval results, data analysis of spatiotemporalvariation, and its relations with emissions and transport, aswell as trend study.
