Summary
Ozone is a harmful air pollutant in the surface atmosphere that affects human health and ecosystems. Ozone is formed in the troposphere as a result of chemical reactions involving two precursor groups, nitrogen oxides (NO x ) and volatile organic compounds (VOCs), under the influence of sunlight. Ozone dry deposition, when vertical transport brings ozone in contact with the Earth surface leading to ozone removal, is an important ozone sink. Deposition to vegetation is a particularly efficient ozone sink, consisting of various pathways, including uptake by plant stomata, deposition to other surfaces in the canopy (e.g., to leaves and to the soil) and chemical removal inside the vegetation canopy. Stomatal ozone uptake can negatively impact photosynthesis, which reduces ecosystem carbon upta
