In this research, we develop a method of eliciting tropospheric ozone and related substances by means of a geostationary satellite making use of simultaneous measurements over multiple spectra (ultraviolet, visible, infrared). We then verify this method by theory and with measurement data. Results demonstrate that we can clearly reveal climatic effects, cross-border pollution and the like by geostationary satellite observation. Simulation results provide a foundation for further hardware design. They also facilitate the determination of optimal observational parameters (temporal/spatial resolution, scanning method, etc.) for specific scientific requirements. Analyses of pre-existing sensor data not only allows us to better access the performance of newly developed sensors, but also leads to new achievements in the field of atmospheric and environmental sciences. Eventually it should enable us to propose an optimal observational method for a futuristic global monitoring system.
