Vegetation is described by stomatal resistance, the vegetation height, the albedo and the aerodynamical properties.
These inputs were used to predict the sensitivity of the plant by predicting the stomatal response to VPD after exposure to ozone.
Since stomatal uptake of ozone by a plant cannot be measured directly, a receptor-specific micrometeorological parametrization is needed.
The stomata are bordered by guard cells andtheir stomatal accessory cells(together known as stomatal complex) that open and close the pore.
The harmful effects of ground-level O3 to vegetation include effects on photosynthetic carbon assimilation, stomatal conductance, and plant growth.
The stomatal DO3SE model was run with both current(1997) and climate change input O3 and meteorological data.
Further work is required to include suitable soil water modelling methods to assess the influence of soil water status on stomatal O3 flux.
It was decided to develop an ozone stomatal flux model for beans to establish whether robust flux-effect relationships could be developed in the future.

Overall, the most important of these is VPD,which tends to increase in parallel with increasing ozone concentrations and limits stomatal conductance and, hence, ozone uptake.
From 1998 to 2001, participants from nine sites collected stomatal conductance measurements according to a standard protocol e.g. ICP Vegetation 2001.
In addition to the timing of exposure, effects of ozone on plants depend on environmental factors,especially factors that influence plant sensitivity via their effect on stomatal conductance.
Comparisons of photosynthesis and multiplicative algorithm-based stomatal flux modelling methods showed that they predicted stomatal conductance equally well.

The poor relationship between ozone sensitivity and stomatal density(Hayes et al. 2007) suggests that physiological controls are unlikely to be simple.
O3-induced leaf injury on(semi-)natural vegetation was widespread across Europe, and had frequently been recorded in regions with low ozone concentrations butmodelled high ozone stomatal fluxes.
Growth characteristics, seed production, differences in stomatal conductance, and physical leaf characters may all contribute to differences in ozone resistance Davison and Barnes, 1998.
Thus, the outcome of this ANN modelling approach has confirmed the importance of the relative growth rate and the stomatal conductance of a species in determining sensitivity to ozone.
This might lead to a change in the stomatal O3 flux if peak O3 concentrations, currently associated with midsummer, coincided with a later developmental stage of the plants.
