Abstract In this study, we simulated heterotrophic CO2(Rh) fluxes at six European peatland sites using the
ECOSSE model and compared them to estimates of
Rh made from eddy covariance (EC) measurements. The sites are spread over four countries with different climates, vegetation and management. Annual Rh from the different sites ranged from 110 to 540 g C m−2. The
maximum annual Rh occurred when the water table
(WT) level was between −10 and −25 cm and the
temperature was above 6.2 °C. The model successfully
simulated seasonal trends for the majority of the sites.
Regression relationships (r2) between the EC-derived
and simulated Rh ranged from 0.28 to 0.76, and the root
mean square error and relative error were small.
