Data sets

Carbon dioxide fluxes and soil, vegetation, meteorological data from a polygonal tundra in northeastern Siberia T. Eckhardt, C. Knoblauch, L. Kutzbach, D. Holl, G. Simpson, E. Abakumov, and E.-M. Pfeiffer

Short summary
We quantified the contribution of individual components governing the net ecosystem exchange of CO2 and how these fluxes respond to environmental changes in a drained and water-saturated site in the polygonal tundra of northeast Siberia. This work finds both sites as a sink for atmospheric CO2 during the growing season, but sink strengths varied between the sites. Furthermore, it was shown that soil hydrological conditions were one of the key drivers for differing CO2 fluxes between the sites.
