Atmospheric CO2 inversions on the mesoscale using data-driven prior uncertainties : quantification of the European terrestrial CO2 fluxes
Optimized biogenic carbon fluxes for Europe wereestimated from high-resolution regional-scale inversions, uti-lizing atmospheric CO2measurements at 16 stations for theyear 2007. Additional sensitivity tests with different data-driven error structures were performed. As the atmosphericnetwork is rather sparse and consequently contains large spa-tial gaps, we use a priori biospheric fluxes to furthe
