How much CO₂ Arctic land takes up or releases (2001-2020)
What it measures. Monthly maps of how much carbon dioxide the Arctic and boreal land absorbs through plant growth versus releases through respiration, plus the net balance, at 1-kilometer detail.
How it's made. Generated with a machine-learning model that combined ground-based CO2 flux measurements with weather, satellite, terrain, and soil data, covering 2001 to 2020.
How & where you'd use it. Helps researchers understand whether northern landscapes are soaking up or giving off carbon and how that is changing, including the effect of fires.

Official description
This dataset provides gridded estimates of gross primary productivity (GPP), ecosystem respiration (Reco), and net ecosystem CO2 exchange (NEE) across the circumpolar terrestrial Arctic-boreal region at a 1-km spatial resolution. Monthly CO2 flux data from 2001 to 2020 were generated using terrestrial eddy covariance and chamber CO2 flux observations, combined with geospatial meteorological, remote sensing, topographical and soil data, all within a random forest modeling framework. Aggregated average annual NEE, average annual NEE with direct fire emissions added based on the Global Fire Emissions Database (GFED) product, and temporal trends in annual NEE rasters over 2002-2020 are also included. The data are provided in NetCDF and GeoTIFF formats.
