Impacts of Biogeochemical River Inputs on Oceanic FCO2 in MPIOM-HAMOCC

Short Description: Impacts of biogeochemical river inputs on the spatial oceanic CO2 flux (FCO2) in the ocean biogeochemistry model HAMOCC at a 1x1° spatial resolution. The flux for each grid point is given as the difference between a preindustrial model simulation accounting for riverine inputs and another one simply compensating burial fluxes spatially (Lacroix et al., 2020). The data is used as river correction flux (Friv) in the Global Carbon Budget 2024 (Friedlingstein et al., 2025).
