In this file, we include the data from the GCB2025 inversions on 1x1 degrees latitude-longitude. The variables include the prior and posterior land biosphere and ocean carbon fluxes. The land biosphere fluxes have been adjusted to a common fossil fuel emissions dataset (land_flux_only_fossil_cement_adjusted). This allows the inverse estimates to be compared to each other within this ensemble. In this case, we apply a fossil fuel and cement adjustment to account for minor remaining differences to GridFED v2025_1 (this GridFED version includes emissions from cement production and a sink from cement carbonation). For a comparison with bottom-up estimates, further adjustments need to be made, for the lateral fluxes, specifically rivers. In contrast to earlier versions of this file, we do not provide the lateral adjusted inverse estimates, since different lateral flux data sets are available. The simulated CO2 mole fractions as sampled from these 14 inverse models are available at https://doi.org/10.18160/4MNF-W5DR (van der Woude et al., 2025).
