“…Ozone is a respiratory irritant to humans, and it damages both natural and man-made materials such as stone, brick-work and rubber (Serrano et al, 1993). All these harmful effects are significant in Southern Europe (Silibello et al, 1998;Grossi et al, 2000;San José et al, 2005) as in summer solar radiation exacerbates the effects of ozone. This is the case in areas of northern Spain located near urban and industrial areas, and especially those lying downwind of such areas, where local ozone precursors are lacking (Soler et al, 2004;Aguirre-Basurko et al, 2006).…”

We examine the ability of a modelling system to forecast the formation and transport of ozone over Catalonia, at the NE of the Iberian Peninsula. To this end, the Community Multiscale Air Quality (CMAQ) modelling system developed by the United States Environmental Protection Agency (US EPA) and the PSU/NCAR mesoscale modelling system MM5 are coupled to a new emission model, the Numerical Emission Model for Air Quality (MNEQA). The outputs of the modelling system for the period from May to October 2008 are compared with ozone measurements at selected air-monitoring stations belonging to the Catalan Government. Results indicate a good behaviour of the model in reproducing diurnal ozone concentrations, as statistical values fall within the EPA and EU regulatory frameworks.

“…Traffic stations were in general discarded for the model evaluation due to their limited spatial representativity although four traffic sites were also employed. In spite of belonging to different air-quality networks ( et al, 2002;San José et al, 2005), and, more specifically, to evaluate the impact of specific environmental policies in the Madrid region (Soret et al, 2014) or the influence of sectoral emissions (Borge et al,10 2014; Valverde et al, 2016;de la Paz et al, 2016;Pay et al, 2018). The present work contributes with an evaluation and optimisation of LOTOS-EUROS CTM in the region incorporating a high degree of vertical configurations using the hybrid-layer scheme (0.750 ± 0.062 -0.801 ± 0.034).…”

Abstract. Tropospheric O3 remains a major air-quality issue in the Mediterranean region. The combination of large anthropogenic emissions of precursors, transboundary contributions, a warm and dry aestival climate and topographical features results in severe cases of photochemical pollution. Chemical transport models (CTMs) are essential tools for studying O3 dynamics and for assessing mitigation measures but they need to be evaluated specifically for each air basin. In this study, we present an optimisation of the LOTOS-EUROS CTM for the Madrid air basin. Five configurations using different meteorological datasets (from the European Centre for Medium Weather Forecast (ECMWF) and Weather Research and Forecasting (WRF)), horizontal resolution and number of vertical levels were compared for July 2016. LOTOS-EUROS responded satisfactorily in the five configurations reproducing observations of surface O3 with notable correlation and reduced bias and errors. However, the best-fit simulations for surface O3 were obtained by increasing spatial resolution and using a large number of vertical levels to reproduce vertical transport phenomena and the formation of reservoir layers. Using the optimal configuration obtained in the evaluation, three characteristic events have been described: recirculation (REC) episodes and northern and southern advection (NAD and SAD, respectively) events. REC events were found to produce the highest O3 due to the reduced ventilation associated with low wind speeds and the contribution of reservoir layers formed by vertical transport of O3 formed near the surface in the previous days of the event. NAD events, usually associated with higher wind speeds, present the lowest ground-level O3 concentrations in the region. During SAD episodes, external contributions along with low wind speeds allow O3 to increase considerably, but not as much as in REC events because steady southerly winds disperse local emissions and hinder the formation of reservoir layers.

“…The warm conveyor belt of a cyclone lofted pollutants responsible for O 3 high concentrations over the western North Atlantic Ocean into the free troposphere [136]. In Europe, exceptional meteorological conditions have been considered to explain very high levels in Madrid, Spain [137]. Air masses from industrialized continental Europe and wildfire emissions determined high O 3 levels in southern Italy, whereas the North African desert region was associated with lower concentrations [138].…”

Air trajectory calculations are commonly found in a variety of atmospheric analyses. However, most of reported research usually focuses upon the transport of pollutants via trajectory routes and not on the trajectory itself. This paper explores the major areas of research in which air trajectory analyses are applied with an effort to gain deeper insights into the key points which highlight the necessity of such analyses. Ranging from meteorological applications to their links with living beings, air trajectory calculations become important tool especially when alternative procedures do not seem possible. This review covers the reports published during last few years illustrating the geographical distribution of trajectory applications and highlighting the regions where trajectory application research proves most active and useful. As a result, relatively unexplored areas such as microorganism transport are also included, suggesting the possible ways in which successful use of air trajectory research should be extended.
