Carbon dioxide exchange at Arctic and northern forest sites (1989-2020)
What it measures. Monthly records of carbon dioxide exchange between land and air at Arctic and northern forest sites, broken into how much carbon plants absorb and how much ecosystems release, plus over 70 supporting site and weather details.
How it's made. Compiled from ground-based flux measurements and supporting environmental data across 244 tundra and boreal sites, standardized into a single monthly database spanning 1989 to 2020.
How & where you'd use it. Used to study how far-northern ecosystems take up and release carbon over decades, valuable for understanding the carbon cycle in a warming Arctic.

Official description
This Arctic-Boreal CO2 fluxes (ABCflux) dataset contains monthly aggregates of terrestrial net ecosystem CO2 exchange and its derived partitioned component fluxes: gross primary productivity (GPP) and ecosystem respiration. Over 70 supporting variables describe key site conditions (e.g., vegetation and disturbance type), micrometeorological and environmental measurements (e.g., air and soil temperatures), and flux measurement techniques. The data contained in this ABCflux dataset form a standardized monthly database of Arctic-Boreal CO2 fluxes (i.e., ABCflux Database) and include 244 sites and 6,309 monthly observations; 136 sites and 2,217 monthly observations represent tundra, and 108 sites and 4,092 observations represent the boreal biome. The data are for the period 1989 to 2020.
