NPP Multi-Biome: Global Net Primary Productivity and Driver Data

81 Class A sites, 933 Class B sites, and 3,855 Class C grid cells provide a refined global dataset of terrestrial net primary productivity (NPP) estimates and model driver data. The data results from the Ecosystem Model-Data Intercomparison (EMDI) workshop review and outlier analyses, building upon the Global Primary Production Data Initiative (GPPDI). It includes NPP, climate, NDVI, land cover, vegetation, and soil data for assessing the accuracy of global carbon cycle model forecasts.

Use Cases

• Validating terrestrial carbon cycle models using the multi-tiered site classification and driver data.
• Analyzing relationships between climate variables and net primary productivity across global biomes.
• Upscaling point measurements to grid cells using the provided Class C 0.5-degree estimates.
• Conducting outlier analysis on NPP estimates following the EMDI workshop methodology.

Strengths

• Includes a large, structured collection of 4,869 distinct data points (81+933+3,855) across three quality tiers.
• Represents a refined, peer-reviewed synthesis from a major scientific initiative (GPPDI/EMDI) with documented revisions.
• Contains multi-faceted driver data (climate, NDVI, land cover, soil) alongside core NPP estimates.

Limitations

• Column names and specific data schema are not provided in the available metadata.
• Sources conflict on the last updated date, with one platform showing 2026-04-09 and another showing 1996-08-01, creating uncertainty about data currency.
• The 'other-license-specified' license requires users to locate the specific terms, which are not detailed here.
