“…The lower 18 O accumulation rates found in wet soils are the first direct measurements of O 3 deposition to soils of different water content in a replicated experiment. The results confirm observations (Turner et al ., 1974) and inferences (Wesely et al ., 1981; Van Pul & Jacobs, 1994; Güsten et al ., 1996) from field data using flux profiles or eddy covariance, which indicate that lower O 3 fluxes to soil occur at high moisture contents. This is probably caused by a reduction in pore volume and hence a lower O 3 diffusivity into soil, although the reaction of O 3 with soil particles may also have been reduced by a water film on particle surfaces.…”

Summary• We show that the stable isotope 18 O can be used to trace ozone into different components of the plant-soil system at environmentally relevant concentrations.• We exposed plants and soils to 18 O-labelled ozone and used isotopic enrichment in plant dry matter, leaf water and leaf apoplast, as well as in soil dry matter and soil water, to identify sites of ozone-derived 18 O accumulation.• It was shown that isotopic accumulation rates in plants can be used to infer the location of primary ozone-reaction sites, and that those in bare soils are dependent on water content. However, the isotopic accumulation rates measured in leaf tissue were much lower than the modelled stomatal flux of ozone.• Our new approach has considerable potential to elucidate the fate and reactions of ozone within both plants and soils, at scales ranging from plant communities to cellular defence mechanisms.

“…However, soil and vegetation remove O 3 from the atmosphere, producing a vertical gradient of decreasing O 3 concentrations towards the ground (Turner et al, 1974) and preventing any appreciable penetration of O 3 into the soil (Blum and Tingey, 1977). Therefore, any direct effects of O 3 on soil microorganisms can be of only minor importance, and the indirect effects of O 3 on microbes arising from its impacts on plants are much more relevant.…”

“…Among gaseous pollutants, tropospheric O 3 is known to contribute to both AQ degradation and atmospheric warming. At high concentrations, O 3 can damage plant tissues resulting in a reduction of agricultural crop yields and forest tree growth (Turner et al, 1974;Krupa et al, 2000). In addition to its direct effect as a warming GHG, O 3 generates an "indirect effect" onto the climate system through feedbacks with the carbon cycle.…”

Online coupled regional meteorology chemistry models in Europe: current status and prospects

Published by Copernicus Publications on behalf of the European Geosciences Union. A. Baklanov et al.: Online coupled regional meteorology chemistry models in EuropeAbstract. Online coupled mesoscale meteorology atmospheric chemistry models have undergone a rapid evolution in recent years. Although mainly developed by the air quality modelling community, these models are also of interest for numerical weather prediction and regional climate modelling as they can consider not only the effects of meteorology on air quality, but also the potentially important effects of atmospheric composition on weather. Two ways of online coupling can be distinguished: online integrated and online access coupling. Online integrated models simulate meteorology and chemistry over the same grid in one model using one main time step for integration. Online access models use independent meteorology and chemistry modules that might even have different grids, but exchange meteorology and chemistry data on a regular and frequent basis. This article offers a comprehensive review of the current research status of online coupled meteorology and atmospheric chemistry modelling within Europe. Eighteen regional online coupled models developed or being used in Europe are described and compared. Topics discussed include a survey of processes relevant to the interactions between atmospheric physics, dynamics and composition; a brief overview of existing online mesoscale models and European model developments; an analysis on how feedback processes are treated in these models; numerical issues associated with coupled models; and several case studies and model performance evaluation methods. Finally, this article highlights selected scientific issues and emerging challenges that require proper consideration to improve the reliability and usability of these models for the three scientific communities: air quality, numerical meteorology modelling (including weather prediction) and climate modelling. This review will be of particular interest to model developers and users in all three fields as it presents a synthesis of scientific progress and provides recommendations for future research directions and priorities in the development, application and evaluation of online coupled models.
