Pan-Arctic Carbon and Methane Flux Gridded Estimates 2003-2015

Simulations from the Arctic Terrestrial Carbon Flux Model provide daily, 1-km resolution gridded estimates of gross primary productivity, ecosystem respiration, net ecosystem CO2 exchange, and methane emissions for tundra and boreal wetland soils north of 49 degrees. The model, developed by ORNL_CLOUD, was calibrated using over 60 tower eddy covariance sites and covers the years 2003 to 2015. Data are available in NetCDF and CSV formats.

Use Cases

• Validating regional climate models against daily GPP and Reco estimates.
• Analyzing spatial patterns of methane emissions from boreal wetland soils.
• Studying the interannual variability of net ecosystem CO2 exchange (NEE) across the pan-Arctic domain.
• Investigating the relationship between vegetation communities (from land cover maps) and carbon flux components.

Strengths

• Model calibration and evaluation leveraged data from more than 60 tower eddy covariance sites.
• Provides a 13-year daily time series (2003-2015) at a high 1-km spatial resolution.
• Carbon pools were initialized using a 1,000-year model spin-up to achieve dynamic steady-state.

Limitations

• Conflicting last updated dates exist across platforms (2015-12-31 vs. 2026-03-13), suggesting potential metadata inconsistency.
• Exact row count, file size, and specific column names are not provided in the available metadata.
• Data is model output, not direct observational measurements.
