Short summary

We report a soil COS flux model that is the first to resolve both vertical transport and microbial sources and sinks in soil and litter. By evaluation with field data, we show that the model can reproduce observed daily and long-term variations of soil COS flux. We also demonstrate that diffusion is important in controlling the flux, by limiting the COS available for soil uptake when there is strong litter uptake and modulating the water content dependence of soil uptake.
