“…The ozone exposure index AOT40 (Accumulation Over a Threshold hourly ozone concentration of 40 ppb) is widely applied . However, as ozone effects on plants depend not only on atmospheric concentrations, but also on ozone uptake through the stomata , stomatal flux-based metrics like the Phytotoxic Ozone Dose above a threshold Y, POD Y have been more recently applied (Gerosa et al, 2015;Hu et al, 2015;Mills et al, 2011). Most studies about ozone exposure-and flux-response relationships are based on crop yields (Betzelberger et al, 2010;Feng et al, 2012;Grunhage et al, 2012;Pleijel et al, 2007), tree biomass and visible injury symptoms (Marzuoli et al, 2009;Sicard et al, 2016).…”

“…2 and 3), although soybean is reportedly more sensitive than maize, based on manipulative dose-response experiments (2). This has important implications for current crop production considering that ground-level [O 3 ] during the Northern Hemisphere growing seasons frequently exceed 40 ppb (4), the threshold concentration for a cumulative exposure index used in Europe, as well as the concentration above which prolonged exposure leads to significant crop yield loss (5,6). Globally, [O 3 ] is projected to increase over this century if current high emissions continue (7).…”

Numerous controlled experiments find that elevated ground-level ozone concentrations ([O3]) damage crops and reduce yield. There have been no estimates of the actual yield losses in the field in the United States from [O3], even though such estimates would be valuable for projections of future food production and for cost–benefit analyses of reducing ground-level [O3]. Regression analysis of historical yield, climate, and [O3] data for the United States were used to determine the loss of production due to O3 for maize (Zea mays) and soybean (Glycine max) from 1980 to 2011, showing that over that period production of rain-fed fields of soybean and maize were reduced by roughly 5% and 10%, respectively, costing approximately $9 billion annually. Maize, thought to be inherently resistant to O3, was at least as sensitive as soybean to O3 damage. Overcoming this yield loss with improved emission controls or more tolerant germplasm could substantially increase world food and feed supply at a time when a global yield jump is urgently needed.

“…Exceedance of the CL and TV was calculated only for wheat because there are insufficient data available to derive neither a critical level specific for trees in the Mediterranean area (LRTAP Convention, 2010;Mills et al, 2011a) nor a specific target value for forests (Directive 2008/50/EC).…”

“…This work allows estimating and comparing the risk of ozone damage on vegetation in the Iberian Peninsula (IP) and Balearic Islands through concentration-based and flux-based approaches integrating both, modelled meteorological conditions and O3 levels. Such development establishes a framework for estimating the risk of ozone impacts on vegetation under different emission/ policy scenarios according to the concentration-response and flux-response relationships derived from experimental studies (Fuhrer et al, 1997;Karlsson et al, 2004;Mills et al, 2007aMills et al, , 2011aLRTAP Convention, 2010;Pleijel et al, 2004).…”

A module to estimate risks of ozone damage to vegetation has been implemented in the Integrated Assessment Modelling system for the Iberian Peninsula. It was applied to compute three different indexes for wheat and Holm oak; daylight AOT40 (cumulative ozone concentration over 40 ppb), cumulative ozone exposure index according to the Directive 2008/50/EC (AOT40-D) and PODy (Phytotoxic Ozone Dose over a given threshold of Y nmol m~2 s _1 ). The use of these indexes led to remarkable differences in spatial patterns of relative ozone risks on vegetation. Ozone critical levels were exceeded in most of the modelling domain and soil moisture content was found to have a significant impact on the results. According to the outputs of the model, daylight AOT40 constitutes a more conservative index than the AOT40-D. Additionally, flux-based estimations indicate high risk areas in Portugal for both wheat and Holm oak that are not identified by AOT-based methods.
