  • Monitoring the global distribution of greenhouse gases using spaceborne observations and attributing regional anomalies of their surface fluxes to either climatic or human processes represents a new frontier in Earth system science. The reduction in economic activity in early 2020 due to the Coronavirus Disease 2019 (COVID-19) pandemic led to unprecedented decreases in monthly carbon dioxide (CO2) emissions from fossil fuel use. This paper shows, for the first time, that the regional impact of COVID-19 was observable from space. Our approach uses data assimilation to ingest satellite observations of column average CO2 (XCO2) from NASA\'s Orbiting Carbon Observatory 2 (OCO-2) into the Goddard Earth Observing System (GEOS), an integrated Earth system model.
