Short summary
Estimates of photosynthesis and respiration at large scales are needed to improve our predictions of the global CO2 cycle. Carbonyl sulfide (OCS) has been proposed as a new tracer of photosynthesis, as it was shown that the uptake of OCS from leaves is nearly proportional to photosynthesis. But soils also exchange OCS with the atmosphere. Here we propose a mechanistic model of this exchange and show, using this new model, how we are able to explain several observed features of soil OCS fluxes.
