This research aims to enhance the estimation of surface CO2 fluxes by utilizing a variational data assimilation framework with dense atmospheric data.
Developed a variational data assimilation scheme for CO2 flux estimation at fine spatial (4° × 5°) and temporal scales (daily).
Quantified flux errors from existing, planned, and hypothetical observation systems.
Simulated the performance of the NASA Orbital Carbon Observatory (OCO) satellite against current in situ measurements.
Achieved rapid global flux estimates after only a few dozen minimization steps.
Identified significant improvements in CO2 flux data from the planned OCO satellite compared to existing observations.
Demonstrated the need for advancements in data assimilation techniques and mechanistic models to utilize global carbon observations effectively.
