Global Gridded Daily Reservoir Methane Emissions Model

Daily climatological methane emission rates from inland dam-reservoir systems are modeled at a 0.25-degree global grid resolution. Estimates are provided for boreal, temperate, and subtropical-tropical eco-climatic domains, derived from daily mean inputs averaged over the period 2002 to 2015. This dataset was produced by the National Aeronautics and Space Administration to assess the role of reservoirs in the global methane budget.

Use Cases

• Modeling the contribution of reservoir emissions to regional and global methane budgets using daily emission rate grids.
• Analyzing seasonal emission patterns across different eco-climatic domains (boreal, temperate, subtropical-tropical).
• Assessing the spatial distribution of methane sources by combining emission rates with the fractional area of reservoirs per grid cell.
• Informing climate mitigation strategies by identifying high-emission reservoir grids for targeted intervention.

Strengths

• Provides global coverage at a consistent 0.25-degree spatial resolution.
• Offers daily climatological values for a full year (n=365 days) for temporal analysis.
• Model inputs are based on a 14-year average (2002-2015), enhancing representativeness.

Limitations

• Specific column names and the total row/record count are not provided by any source.
• Conflicting last updated dates exist between platforms (2015-12-31 vs. 2026-03-13), creating uncertainty about metadata freshness.
