Incorporation of NPP into forest CH4 efflux models

Forest soils are the largest atmospheric methane (CH4) sinks in terrestrial ecosystems, but models simulating this uptake have considerable uncertainties. Soil organic matter derived from aboveground vegetation net primary productivity (NPP) significantly influences CH4 uptake; therefore, we propose that the incorporation of NPP into global CH4 uptake models will greatly improve model predictions.
