Space-based detection and monitoring of tropospheric ozone is critical for enhancing scientific understanding of creation and transport of this important trace gas and for providing data needed to help develop national and international strategies for mitigating impact of exposure to elevated concentrations of tropospheric ozone in the US and elsewhere. Spaceflight instrument concept studies presented here show that a spaceborne imaging Fabry-Perot interferometer to measure tropospheric ozone from geosynchronous earth orbit is feasible and can be ready for full scale development starting in 2007.
