Regional air-sea fluxes of anthropogenic carbon inferred with an Ensemble Kalman Filter
[1] Regional air-sea fluxes, ocean transport, and storage of anthropogenic carbon (Canth) are quantified. Observation-based Canth data from the ocean interior are assimilated into the Bern3D dynamic ocean model using an Ensemble Kalman Filter. Global uptake of Canth is estimated to be 131 ± 18 GtC o...
