Atmosphere‐wetland carbon exchanges: Scale dependency of CO2 and CH4 exchange on the developmental topography of a peatland

Measurement of the spatial variability of CH 4 emissions and net CO 2 ecosystem exchange were made in a boreal peatland in northern Sweden in the summers of 1992 and 1993. Variability was monitored at the microscale (hummocks and hollows), mesoscale (ridges, lawns and pools), and macroscale (landforms) to assess the role of peatland topography on the magnitude and variability of the fluxes. The general trend is for topographically lower areas, …
