CoCO2: Methane Emissions Data for Eight Large Global Emitters

CoCO2 project data reconciles observation- and inventory-based methane emissions for eight major emitting countries. The spreadsheets contain CH4 data behind manuscript figures, presented as time series, mean values, and uncertainty ranges. This synthesis is based on data from the VERIFY project for the EU27 and deliverables from the CoCO2 project funded by the European Commission.

Use Cases

• Reconcile top-down atmospheric observations with bottom-up inventory estimates based on the described synthesis methodology.
• Analyze temporal trends in methane emissions based on the provided time series data.
• Quantify uncertainty in national emissions reporting based on the included min-max ranges.
• Validate satellite-derived methane flux estimates for large emitters based on the gridded data mentioned.

Strengths

• Includes uncertainty quantification with min and max ranges for emissions values.
• Synthesizes data from two established scientific projects, VERIFY and CoCO2.
• Covers eight of the world's largest methane-emitting countries.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Gridded data requires direct contact with providers, limiting immediate access.
