The NASA Carbon Monitoring System Flux (CMS-Flux) is a global
carbon cycle data assimilation system that quantifies the spatial
and process drivers of atmospheric CO2. To that end, CMS-Flux
provides a framework to constrain a suite of terrestrial, ocean,
atmospheric, and anthropogenic carbon cycle models with a diverse
set of satellite observations enabled by state-of-the-art
assimilation algorithms. This framework leads to a consistent,
comprehensive description of the carbon cycle that enables process
understanding and improved prediction.
The NASA CMS methane project utilizes the same assimilation and chemical transport modeling capabilities as CMS-Flux but focuses on satellite and ground measurements of methane and corroborative tracers in conjunction with state-of-the-art “bottom-up” inventories of anthropogenic and natural methane emissions. These inventories are available to initialize “top-down” flux estimates and contribute to local and regional methane budgets.
We encourage you to review the publications describing CMS-Flux and CMS Methane to understand its capabilities and limitations. A data portal is available to download component fluxes and user description.
