This article addresses the reporting requirements concerning ambient ozone and will be repealed as from 1 January 2014, i. e. two years after entry into force of the implementing measures of Directive 2008/50/EC.

Information on the situation in Slovakia was received one month later; unfortunately too late to include fully in this report… 984 + 100 stations All information has been submitted in computer readable form. The spatial coverage and quality documentation of the data need further improvement.

Following preliminary results are based on data received before 24 th October 2013, i. e. partly without September data. The information describing the situation during the summer is based on tentatively validated and non-validated monitoring data and hence should be regarded as preliminary (the level and extent of validation is not reported by the countries).
