Short summary

Carbonyl sulfide (COS) can be used as a proxy for plant photosynthesis on an ecosystem scale. However, the relationships between COS and CO₂ fluxes and their dependence on daily to seasonal changes in environmental drivers are still poorly understood. We examined COS and CO₂ ecosystem fluxes above an agriculturally used mountain grassland for 6 months. Harvesting of the grassland disturbed the otherwise stable COS-to-CO₂ uptake ratio. We even found the canopy to release COS during those times.
