G.   Promotion of harmonised air quality modelling approaches

To promote and support the harmonised use of scientifically sound air quality modelling approaches by the competent authorities with an emphasis on model application, the appropriate competent authorities and bodies designated pursuant to Article 5 shall ensure the following:

(a)

that the designated reference institutions participate in the European network of air quality modelling set up by the JRC;

(b)

that best practices in air quality modelling identified by the network through scientific consensus are adopted in relevant applications of air quality modelling for the purposes of fulfilling legal requirements pursuant to Union legislation, without prejudice to model adaptations necessitated by singular circumstances;

(c)

that the quality of relevant applications of air quality modelling is periodically checked and improved through intercomparison exercises organised by the JRC;

(d)

that the European network of air quality modelling be responsible for the periodic review, at least every 5 years, of the maximum ratio of modelling uncertainties listed in Point A, Tables 1 and 2, of this Annex and subsequent proposal of any necessary changes to the Commission.

(1)  When using indicative measurements for purposes other than compliance assessment, such as, but not only: design or review of the monitoring network, calibration and validation of modelling applications, the uncertainty may be that established for modelling applications.

(2)  When using indicative measurements for purposes other than compliance assessment, such as, but not only: design or review of the monitoring network, calibration and validation of modelling applications, the uncertainty may be that established for modelling applications.

(3)  The threshold shall be set to 4, 3, 10, 3 and 5 μg/m3 for PM10, PM2,5, O3, NO2 and SO2, respectively, and 0,5 mg/m3 for CO. These values represent the state of knowledge and shall be regularly updated at least every 5 years, to reflect developments in the state of the art.

(4)  For O3, minimum data coverage requirements are to be met both for the full calendar year, and for the periods of April to September, and October to March, respectively.

Assessment of the AOT40 for ozone minimum data coverage requirements are to be met during the time period defined for calculating the AOT40 value.

(5)  For O3, minimum data coverage applies for the period of April to September (no criterium of minimum data coverage is required during the winter period).

(6)  Regulation (EC) No 765/2008 of the European Parliament and of the Council of 9 July 2008 setting out the requirements for accreditation and repealing Regulation (EEC) No 339/93 (OJ L 218, 13.8.2008, p. 30).
