The GeoCarb Mission

The community has been measuring greenhouse gases from space for two decades, starting with SCIAMACHY and proceeding through GOSAT, OCO-2, TROPOMI, GOSAT-2, OCO-3, with many more to come in the future. The GeoCarb mission was selected in 2016 under the Earth Venture Mission program by NASA. GeoCarb will measure CO2, CH4, and CO from geostationary orbit aboard a commercial communications satellite as a hosted payload starting in 2023. In this presentation, we will discuss mission technical progress and program updates, including the recent passage into Phase C on Jan 1, 2020 and plans moving forward with integration and test and eventual launch. Additionally, we will discuss plans for how best to proceed in this brave new world of a true constellation of greenhouse gas sensors, including cross-calibration and use of the data for flux determination.
