This report is based upon data submitted to the European Commission under Directive 92/72/EEC on air pollution by ozone. In this topic report, the annual 1998 and summer 1999 reports as presented to the Commission are reproduced here in an updated version. New information which became available...

Summary of a draft report to the European Commission giving a preliminary evaluation of ozone pollution across Europe in spring and summer 2003. The report is based on data provided up to 15 September by countries in the framework of Council Directive 92/72/EEC on air pollution by ozone.

In summer 2004, the levels of ground-level ozone were high in southern Europe with widespread exceedances of the information threshold value (180 µg/m3), as laid down in the ozone directive (2002/3/EC). The exceedances of the information threshold were similar to earlier years, except for...

In summer of 2005 levels of ground-level ozone were high in southern Europe with widespread exceedances of the information threshold value (180 micro g/m3) laid down in the ozone directive (2002/3/EC). The frequency of exceedances of the information threshold was similar to earlier years, except...

In summer 2006, levels of ground-level ozone were high in southern Europe and north-western Europe, with widespread exceedances of the information threshold value (180 μg/m3, Directive 2002/3/EC). The frequency of these exceedances was higher than those in previous years, though not as high as...

Ozone levels during the summer of 2007 were among the lowest in the past decade.. The number and spatial extent of exceedances was lower than in any of the last ten summers. In contrast to the summer of 2006, no exceedances of the information threshold value (180 microgram/m3, Directive...

This report gives an overview of reported ground-level ozone concentrations between April and September 2008, and provides a comparison with the last ten years.

In this study, long-term measurements of rural background ozone levels are analysed and compared with modelling results and sensitivity analyses. Rural background stations are used in order to rule out the influence of local conditions close to sources of ozone precursors (mainly traffic)....

This report presents particulate matter (PM10) and ground‑level ozone concentration maps covering the whole of Europe. The interpolated maps are based on a combination of measurement and regional modelling results. Using measured concentrations as a primary source of information, the report...

Ozone levels during summer 2009 were as low as during summer 2008 and according to several indicators were among the lowest since reporting of Europe-wide data commenced in 1997. In contrast to previous summers, in 2009 there were no pan-European multi-day episodes. Summer 2009 was characterised...
