Short summary

Carbonyl sulfide (COS) is an emerging tracer to probe land photosynthesis at canopy to global scales, but the relationship between leaf COS and CO₂ fluxes needed for this application is poorly quantified. With in situ leaf fluxes of COS and CO₂ measured in a freshwater marsh, we show that light and vapor deficit control the relationship between leaf COS and CO₂ fluxes by regulating stomatal conductance. Our findings support the use of COS as a tracer for canopy photosynthesis.
