 This study investigates the effect of model resolution on wetland methane emissions. The authors found that higher resolutions lead to better predictions of wetland emissions, but that these predictions can still be affected by uncertainties in the wetland area. They suggest that increasing the resolution of global wetland models should be given high priority in order to reduce the effects of uncertainties in wetland area.
