TVPRM Simulated Net Ecosystem Exchange for Alaskan North Slope, 2008-2017

NASA's ABoVE project provides hourly net ecosystem exchange (NEE) simulations for the Alaskan North Slope from 2008 to 2017. The Tundra Vegetation Photosynthesis and Respiration Model (TVPRM) generated these 30 km resolution estimates using functional relationships from eddy covariance towers, scaled with gridded meteorology and vegetation maps. The dataset includes an ensemble of 288 different simulation variations exploring different ecological behaviors and environmental drivers.

Use Cases

• Modeling regional carbon budgets based on simulated hourly net ecosystem exchange.
• Analyzing the impact of different meteorological reanalysis products (NARR, ERA5) on flux estimates.
• Comparing carbon flux dynamics between inland and coastal tundra ecosystem groups.
• Assessing the influence of different vegetation maps (CAVM, RasterCAVM, ABoVE-LC) on model outputs.
• Investigating the effect of including aquatic and zero curtain fluxes on simulated regional CO2 flux.

Strengths

• Provides a 10-year time series (2008-2017) of hourly simulated data.
• Includes an ensemble of 288 different model simulations exploring parameter and driver variations.
• Model relationships are derived from empirical eddy covariance tower measurements.
• Covers the Alaskan North Slope at a consistent 30 km horizontal resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data is simulated model output, not direct observational measurements.
