Interpretive Summary: Ground level ozone is widely recognized as the most damaging air pollutant to crops. However, our ability to accurately model the effects of ozone on crop systems is currently limited. This review describes the physiological mechanisms by which ozone damages crops and discusses the potential to incorporate these responses into process-based crop models.

Technical Abstract: This paper examines steps to develop and incorporate modules and parameterisations capable of simulating ozone damage into existing crop growth models. First, we review our current understanding of how ozone causes damage at the cellular level and describe the current ‘process-based’ modelling methods that have been developed to simulate these mechanisms. We then identify additional features of ozone damage that scale to the whole canopy and indicate the factors that need to be taken into consideration to model these processes and feedbacks. This includes damage caused directly by ozone as well as environmental conditions that might influence the sensitivity of crops to ozone, or result in feedbacks that could enhance or dampen ozone damage. With this understanding, we identify a number of plant physiological traits that might enhance (or reduce) ozone sensitivity and consider how future global climate change might influence ozone sensitivity. Finally, we consider existing crop models and, assess their suitability to incorporate these ozone damage mechanisms and review past and current efforts underway to incorporate the influence of ozone. A summary of priorities for future modelling is provided to guide research in this area.
