CO 2 and CH 4 exchange are strongly affected by hydrology in landscapes underlain by permafrost. Hypotheses for these effects in the model ecosys were tested by comparing modeled CO 2 and CH 4 exchange with CO 2 fluxes measured by eddy covariance from 2006 to 2009, and with CH 4 fluxes measured with...
