Global Gridded Net Primary Productivity Estimates Across Biomes, 1954-1998

3,654 half-degree grid cells provide estimates of net primary productivity (NPP), elevation, temperature, precipitation, NDVI, and biome type for selected terrestrial regions worldwide. The data synthesizes field inventories, literature, models, and remote sensing from 15 sources across a 44-year period. A refined subset of 2,335 unique cells is also provided for model inter-comparisons, with values ranging from 3 to 1,235 grams of carbon per square meter per year.

Use Cases

• Calibrating Earth system models using gridded NPP, temperature, and precipitation columns.
• Analyzing biome-level productivity trends by linking NPP values with the biome type classification.
• Studying the relationship between vegetation indices (NDVI) and carbon production (ANPP/TNPP) across global grids.
• Assessing environmental drivers of productivity through regression analyses using elevation, temperature, and precipitation variables.
• Comparing forest versus rangeland carbon sequestration using the provided ANPP and TNPP ranges.

Strengths

• Data integrates 15 worldwide field sources, providing a multi-source foundation for estimates.
• Offers two analysis-ready files: one with 3,654 cells for broad analysis and a refined set of 2,335 unique cells for precise comparisons.
• Covers a long temporal range (1954-1998) across several biomes, enabling historical trend analysis.
• NPP values are derived through multiple methods including field inventories, simulation models, and remote sensing correlations.

Limitations

• Conflicting metadata: the 'last updated' date differs significantly between Data.gov (2026) and NASA Earthdata (1998).
• Specific column names and the exact license terms are not provided in the available descriptions.
• Data is limited to selected terrestrial regions and does not provide global complete coverage.
