Multi-Biome NPP Summary from 125 Global Sites (1936-2006)

NASA's NPP Multi-Biome dataset provides site-level summary statistics from 125 intensive study sites across five major biomes: boreal forest, grassland, temperate forest, tropical forest, and tundra. It aggregates key ecological measurements including biomass, net primary productivity, climate variables, and site characteristics. The data spans a 70-year period from 1936 to 2006, with global spatial coverage.

Use Cases

• Comparing average annual above-ground Net Primary Productivity (NPP) across boreal, temperate, and tropical forest biomes.
• Analyzing relationships between mean annual precipitation, air temperature, and biomass at grassland and tundra sites.
• Mapping the global distribution of study sites and their dominant soil types or ecoregion classifications.
• Investigating long-term site management history and its potential impact on reported biomass and NPP values.

Strengths

• Includes data from 125 distinct study sites, enabling broad cross-biome comparisons.
• Provides a 70-year temporal range (1936-2006) for understanding long-term ecological patterns.
• Contains multiple integrated variables per site: geolocation, climate, soil, vegetation type, biomass, and NPP.

Limitations

• Exact row count and column names are not specified in the available metadata.
• There is a conflict in the 'last updated' date between platforms (2006 vs. 2026), suggesting potential metadata inconsistency.
• Study periods and sampling intervals vary by site, complicating direct temporal comparisons.
