1. I. Overview status on use of modelling in the implementation of the CAFE Directive
Fairmode WG1 agreed to compile an updated overview of the use modelling by MS for each of these themes:
Theme 1: Assess air quality levels: establish the extent of exceedances
Theme 2: Forecast air quality levels
Theme 3: Source allocation: determine of the origin of exceedances
Theme 4: Elaborate and test plans and measures to control AQ exceedances
As response to the identified need for clarity in the AQ Directive text on when, how and what models will be applied

2. II. Strengthen the use of modelling in the review of the CAFE Directive
Fairmode WG1 agreed to recommend strengthening the recommendations on the use of modelling for the following themes:
Theme 1: Assess air quality levels: establish the extent of exceedances
Theme 2: Forecast air quality levels
Theme 3: Source allocation: determine of the origin of exceedances
Theme 4: Elaborate and test plans and measures to control AQ exceedances
As response to the discussion on the need for “mandatory” use of models in the AQ Directive text

3. III. AQ Model Quality Objectives
Fairmode WG1 recognised that strengthening for use of models imposes further requirements on model quality objectives Fairmode WG1 recommended to include a general reference in the revised Directive on the need to support the activities of a model quality assessment fora (FAIRMODE) where model quality objectives, good practices and benchmarking activities are coordinated securing the comparability of models.

4. IV. Additional Issues
The revised Directive should motivate the combined use of models and measurements
To secure that monitoring takes place in areas where modelling indicates possible exceedances
To secure that when exceedances occur, modelling is used to determine the spatial and temporal extent of these exceedances
