Over the past decades, the eddy covariance (EC) community has clearly demonstrated the power of networks; regional networks and FLUXNET have shown us that combining data across multiple sites creates a whole that is greater than the sum of its parts. The FLUXNET database has been used extensively to evaluate satellite measurements, inform Earth system… More

Releases of the greenhouse gases carbon dioxide (CO2) and methane (CH4) from thawing permafrost are expected to be among the largest feedbacks to climate from arctic ecosystems. However, the current net carbon (C) balance of terrestrial arctic ecosystems is unknown. Recent studies suggest that these ecosystems are sources, sinks, or approximately in balance at present….
