Biosphere-atmosphere exchange of CO2 and its interaction with climate drivers is an important player in the carbon cycle. To estimate net ecosystem exchange (NEE) fluxes, VERIFY includes both biospheric models for bottom-up estimation of fluxes and a regional inversion for a top-down estimation.
The Jena CarboScope-Regional (CSR) inversion system has been deployed for the 2006-2019 period to estimate biosphere-atmosphere exchange fluxes from the top-down perspective, using recent atmospheric observations up to 2019. This deliverable provides details about the inversion. The results include a priori fluxes (used as initial guess) from the diagnostic light use efficiency model VPRM and FLUXCOM model, and posterior fluxes from the CSR inversion.
