Methane emissions data from nine anthropogenic sectors, including industry, agriculture, and waste treatment. The inventory provides global annual totals for 1990 and 1995, developed by the EDGAR/RIVM and GEIA projects under the IGBP/IGAC. Data includes regional summaries and a 1x1 degree spatial grid.
Use Cases
- Modeling atmospheric methane concentrations using the 1x1 degree gridded emission data as input.
- Analyzing sectoral contributions to global methane budgets from features like agriculture, industry, and biomass burning.
- Comparing national or regional emission trends between 1990 and 1995 for policy assessment.
- Validating other emission inventories against the EDGAR data, which has been used in IPCC assessments.
Strengths
- Covers nine specific anthropogenic source sectors.
- Provides data on both a regional level and a 1x1 degree global grid.
- Database was validated with an uncertainty analysis, as referenced in Olivier et al., 2001.
Limitations
- Temporal coverage is limited to two snapshot years, 1990 and 1995.
- No data provided for years after 1995, limiting analysis of recent trends.
- Specific row counts, column details, and sample sizes are not disclosed.
