Atmospheric pollution has been the focus for the global environment ch ange. The traditional groundbased monitoring of the atmospheric pollution can not satisfy the demand of science research and decisionmaking of government. Th e technology for trace gas remote sensing based on the satellite monitoring has p layed an important role in pollution monitoring, which can get the temporal and spatial variation of pollution in longtime series and the trend of the [JP2]tr acegas change.So the study of global biogeochemical cycle and climate chang e can be done with these technologies and data. The instrument for trace gas monitoring on satellite and the data processing were reviewed. The p rospects for trace gas remote sensing by our own satellite instruments and the t race gas research projects are also outlined.
