Publication The application of models under the European Union's Air Quality Directive: A technical reference guide
This technical reference guide provides a general overview of the use of models with regard to the consolidated Directive 2008/50/EC on ambient air quality and cleaner air for Europe (the AQ Directive). This report is an output of the Forum for Air Quality Modelling in Europe (Fairmode) established in 2008 as a joint action of the European Environment Agency (EEA) and the European Commission's Joint Research Centre (JRC).

Highlight Using models for air quality assessment and planning: a guide
Computer models are increasingly used for estimating air quality or forecasting changes in pollution levels. Various different models are currently used across Europe. The new FAIRMODE reference guide aims to make these models comparable, well documented and validated in order to achieve reliable results.

Figure PM2.5 - Annual target value for the protection of human health
In the air quality directive (2008/EC/50), the EU has set a target value for fine particulate matter (PM2.5) for the protection of human health: the PM2.5 annual mean value may not exceed 25 micrograms per cubic metre (µg/m3).

Figure Ozone - Target value for the protection of vegetation
In the air quality directive (2008/EC/50), the EU has set a target value and a long term objective value for ozone (O3) for the protection of vegetation. Target value: the AOT40 may not exceed 18000 (µg/m3) per hour in the period from 1 May to 31 July averaged over five years. Long term objective value: the AOT40 may not exceed 6000 (µg/m3) per hour in the period from 1 May to 31 July within a calendar year. AOT40 (expressed in (μg/m3) ∙ hours) means the sum of the difference between hourly concentrations greater than 80 μg/m3 (= 40 parts per billion) and 80 μg/m3 over a given period using only the one-hour values measured between 8.00 and 20.00 Central European Time (CET) each day. More information is provided in Annex VII of directive (2008/EC/50).

Figure Benzene - Annual limit value for the protection of human health
In the air quality directive (2008/EC/50), the EU has set a limit value for benzene (C6H6) for the protection of human health: the annual mean value may not exceed 5 micrograms per cubic metre (µg/m3). The limit value comes into effect for data measured from 1 January 2010. During 2009 a margin of tolerance was in place so the annual mean should not exceed 6 micrograms per cubic metre (µg/m3).

Figure Ozone - 8 hour mean target value for the protection of human health
In the air quality directive (2008/EC/50), the EU has set a target value and a long term objective value for ozone (O3) for the protection of human health. Target value: the maximum daily eight-hour mean may not exceed 120 micrograms per cubic metre (µg/m3) on more than 25 days per calendar year averaged over three years. Long term objective value: the maximum daily eight-hour mean may not exceed 120 micrograms per cubic metre (µg/m3) within a calendar year.

Figure Nitrogen oxide - Annual limit value for the protection of vegetation
In the air quality directive (2008/EC/50), the EU has set a critical level for nitrogen oxides (NOx) for the protection of vegetation within the zones designated by member states: the NOx annual mean value may not exceed 30 micrograms per cubic metre (µg/m3).

Figure Arsenic - Annual target value for the protection of human health
In the directive 2004/107/EC (Fourth Daughter Directive), the EU has set a target value for arsenic (As) for the protection of human health: the As annual mean value may not exceed 6 nanograms per cubic metre (ng/m3). The target value enters into force 31.12.2012.

Figure Benzo(a)pyrene - Annual target value for the protection of human health
In the directive 2004/107/EC (Fourth Daughter Directive), the EU has set a target value for polycyclic aromatic hydrocarbons (PAH) for the protection of human health; the target is defined in terms of concentration of benzo(a)pyrene (BaP) which is used as a marker substance for PAHs generally: the BaP annual mean value may not exceed 1 nanogram per cubic metre (ng/m3). The target value enters into force 31.12.2012.

Figure Nickel - Annual target value for the protection of human health
In the directive 2004/107/EC (Fourth Daughter Directive), the EU has set a target value for nickel (Ni) for the protection of human health: the Ni annual mean value may not exceed 20 nanograms per cubic metre (ng/m3). The target value enters into force 31.12.2012.
