Description:Atmospheric inversion estimates of net ecosystem exchange (NEE) of CO2 are increasingly relevant to climate policy. We evaluated sub-continental, seasonal estimates of CO2 NEE from nine global inversion systems that participated in the Orbiting Carbon Observatory-2 model intercomparison project (OCO-2 v9 MIP), using 98 research flights conducted over the central and eastern United States from 2016 to 2018 as part of the Atmospheric Carbon and Transport - America mission. We found that the seasonal amplitude of NEE in the central and eastern United States is underestimated in these models and model-data biases are largest for those inversions with the smallest seasonal flux amplitudes. These results were
