This discussion was based on the background document “Review on modelling atmosphere-biosphere exchange of Ozone and Nitrogen oxides”, which reviews the processes contributing to biosphere-atmosphere exchange of O3 and NOx, including stomatal and non-stomatal exchange of O3 and NO, NO2. Non-stomatal exchange, including soil and chemical reactions in the canopy airspace is discussed, with a focus on how these processes are influenced by turbulent transport in the canopy. Existing models are reviewed, from big-leaf and two layer resistance to multi-layer models. Based on this background document, the discussion in the working group was organized to discuss the current gaps in modelling O3-NO-NO2 exchange and the ideal model that should be developed.
