BigFoot Daily Meteorological Data for Nine Biome Sites

Daily meteorological measurements compiled for nine EOS Land Validation Sites across North and South America from 1991 to 2004. The dataset supports ecosystem process modeling for scaling GPP and NPP products and monitoring interannual variability. Data were aggregated from various agencies and co-located CO2 flux towers to a common daily time step for use in the BIOME-BGC model.

Use Cases

• Running the BIOME-BGC ecosystem process model for scaling Gross Primary Productivity (GPP) and Net Primary Productivity (NPP) products.
• Monitoring interannual variability in meteorological conditions across Arctic, boreal, temperate, desert, and tropical biomes.
• Testing and calibrating models that require inputs like surface temperature, precipitation, evapotranspiration, and photosynthetically active radiation.
• Analyzing daily climate trends at specific, representative validation sites from Alaska to Brazil.

Strengths

• Covers nine distinct biome sites, including Arctic tundra, boreal forest, temperate cropland/forest, desert grassland, and tropical forest.
• Provides a consistent daily time series across a 14-year period from 1991 to 2004.
• Data were aggregated from multiple authoritative sources, including agencies and co-located CO2 flux measurement towers, for model compatibility.

Limitations

• The exact row count, column names, and dataset size are not specified across any platform.
• Conflicting last updated dates exist: one source lists 2004-12-31, while others list 2026 03-13, suggesting possible metadata inconsistencies.
