Abstract:
The European Air Quality Directive (2008/50/EC) sets limit values for the concentration of Nitrogen Dioxide (NO2). It is a requirement that all air quality zones and agglomerations assess the levels of NO2 and report these to the European Commission. If NO2 concentrations are found to exceed these limit values then the Member States are obliged to take appropriate steps to reduce these concentrations. In order to do this effectively, air quality management plans must be developed and possible measures assessed. Air quality modelling then becomes an essential tool for local and national authorities to manage their air quality.

This document provides initial guidance on the use of models for air quality assessment and planning, with particular regard to modelling NO2 concentrations. The document is intended as guidance for authorities and modellers to help stimulate ‘good practise’ in air quality modelling and provide an overview and description of methods and tools available for air quality modelling. Since NO2 is generally a local and urban scale problem, this document concentrates on applications within cities.

Prepared by: EEA's European Topic Centre on Air and Climate Change (ETC/ACC) with Bruce Denby (NILU) as editor and many contributors of which several from the ETC/ACM Consortium.
