The land‐atmosphere exchange of methane (CH4) and carbon dioxide (CO2) in a high‐Arctic wet tundra ecosystem (Rylekærene) in Zackenberg, north‐eastern Greenland, was studied over the full growing season and until early winter in 2008 and from before snow melt until early winter in 2009. The eddy cov...
