Air pollution by ozone across Europe during summer 2013 : overview of exceedances of EC ozone threshold values: April-September 2013

This report provides an evaluation of ground-level ozone pollution in Europe during the period from April to September 2013, based on information officially submitted by EU Member States and other reporting countries to the European Commission under Directive 2002/3/EC of the European Parliament and of the Council of 12 February 2002 relating to ozone in ambient air (EC, 2002), and Directive 2008/50/EC (EC, 2008). Since reporting countries have not yet validated submitted data for 2013, the conclusions drawn in this report should be considered preliminary.
