VEMAP Georeferencing Data for Ecosystem Model Intercomparison

VEMAP Phase I Database provides georeferencing and cell area variables for modeling ecosystem responses to environmental change. This multi-institutional, international project supports the intercomparison of biogeochemistry and vegetation distribution models. The dataset was revised in 2002 and is distributed by the Oak Ridge National Laboratory Distributed Active Archive Center.

Use Cases

• Intercomparison of biogeochemistry model outputs using standardized georeferencing variables.
• Sensitivity analysis of vegetation-type distribution models to altered climate forcing.
• Spatial analysis of ecosystem responses using the provided cell area and geolocation data.

Strengths

• Dataset is the product of a multi-institutional, international collaboration, indicating peer-reviewed methodology.
• Includes specific variables for georeferencing and cell area calculations, enabling spatial analysis.
• Cross-platform presence on Data.gov and NASA EarthData signals its established use in the scientific community.

Limitations

• Sources conflict on last updated date: Data.gov lists 2026-03-12, while NASA EarthData lists 1990-12 31.
• No column names, row counts, or specific file sizes are provided on any platform, limiting technical assessment.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
