This study applies Orbiting Carbon Observatory ‐2 (OCO ‐2) column ‐averaged dry ‐air mole fractions of CO 2(XCO 2) to constrain CO 2fluxes during the 2018 Kilauea volcano eruption. CO 2 enhancements ( ΔXCO 2)o f1 –2 parts per million were observed far downwind of the eruption coincident with elevated sulfur dioxide (SO 2) concentrations. The estimated CO 2emission rate was 77.1 ± 49.6 kilotons per day (kt day−1) on 11 July 2018 with most of the uncertainty from modeled winds and XCO 2retrievals. This emission rate is higher compared to flux estimates made with ground ‐based measurements (30–40 kt day−1). However, cross ‐sectional flux estimates made using OCO ‐2 XCO 2observations will
