Global Net Primary Productivity Estimates for Grassland, Tropical, and Boreal Forest Sites

53 sites worldwide provide compiled estimates of net primary productivity (NPP) for 34 grasslands, 14 tropical forests, and 5 boreal forests. The dataset includes site location, biome type, and climatic variables like mean annual precipitation and temperature, where available. NPP values, compiled from published literature, range from 35 to 3,538 grams per square meter per year.

Use Cases

• Modeling terrestrial carbon sequestration based on biome-specific NPP ranges.
• Comparing aboveground and belowground biomass production across grassland, tropical, and boreal forest ecosystems.
• Analyzing the relationship between NPP and climatic factors like mean annual precipitation and temperature.
• Validating remote sensing or process-based model outputs against ground-based NPP compilations.

Strengths

• Covers a specific, global set of 53 field sites across three major biomes.
• Provides explicit NPP value ranges: ANPP (35-2,320), BNPP (20-1,832), TNPP (182-3,538) g/m²/year.
• Includes revised data for specific sites with documented correction notes.
• Originates from a authoritative source (NASA).

Limitations

• Key metadata like row count, column names, and exact file size are missing from all platform entries.
• Conflicting 'last updated' dates exist between sources (1996 vs. 2026), suggesting potential metadata errors.
• Data is compiled from literature up to 1996, limiting contemporary relevance for recent climate studies.
