Comparison of different stomatal conductance algorithms for ozone flux modelling. In: Wieser, G.; Tausz, M., eds. Proceedings on the workshop: Critical Levels of Ozone: Further Applying and Developing the Flux-based Concept; 15-19 November 2005; Obergurgl, Tyrol, Austria. Vienna, Austria: Federal Research and Training Centre for Forests, Natural Hazards and Landscape (BFW). p. 133-139.

The ozone deposition model (D03SE) that has been developed and applied within the EMEP photooxidant model (Emberson et al., 2000, Simpson et al. 2003) currently estimates stomatal ozone flux using a stomatal conductance (gs) model based on the multiplicative algorithm initially developed by Jarvis (1976). This model links gs to environmental and phenological parameters with a set of response functions. However, there exist a number of alternative and well established methods to calculate gs, with the photosynthesis-based algorithm becoming increasingly more popular in situations where carbon-energy flux modelling is required at the regional or global scale.

Keywords: ozone flux modelling, ozone deposition model, EMEP photooxidant model
