Short summary
The major findings of this article are the following. 1. Atmospheric CO2 observations alone are not sufficient to estimate the spatial distribution of carbon sources and sinks over North America, even though it is one of the most densely observed regions in the world. 2. To improve atmospheric inversion, lateral carbon transfer in agricultural products should be considered in the prior flux used to constrain the inversion.
