Prior estimates for fossil fuel carbon flux produced by NASA's Carbon Monitoring System. The dataset is generated by the GES DISC organization and was last updated in December 2022.
Use Cases
- Initialize or constrain atmospheric inversion models using the fossil fuel flux prior.
- Compare posterior flux estimates from CMS against this fossil fuel prior to assess model performance.
- Analyze spatial patterns of fossil fuel emissions implied by the prior data layer.
- Integrate the prior flux data with satellite observations for carbon source and sink characterization.
Strengths
- Data product from NASA's official Carbon Monitoring System.
- Designed to support national and international policy and regulatory activities.
- Maintains a global emphasis while providing finer-scale regional information.
Limitations
- Specific data volume, resolution, and temporal coverage are not detailed.
- Uncertainty estimates for the prior flux values are not described.
- Data is not updated in real-time; the last update was in 2022.
