FAIRMODE WG2 The main aim of WG2 activities is to create a European Framework for Model Evaluation which will include the development of widely accepted quality assurance procedures throughout Europe for different models (regional, urban and local/hotspot) and for different purposes according to the requirements of the AQD (air quality assessment scenario calculations and impact modeling, forecast of exceedances and assessing contribution from natural sources and winter sanding/salting).

Current Structure Role of WG2: Coordinate activities of SGs WG2 SG1:Combined use of monitoring and modelling SG4:Tools for benchmarking of air quality models SG3: Urban emissions and projections SG2:Contribution of natural sources and source apportionment Role of WG2: Coordinate activities of SGs Monitoring compliance to Fairmode mission Harmonize outcome in visible product to science and policy communities Promote results outside WG2 Communication with WG1 facilitate interaction among SGs Looking for ways for financing activities

SG discussions guidelines 1/3 The research performed in WG2 should be in support of a better definition of the AQD in all those components that are still not precisely defined or agreed upon So far most of the groups have conducted very important literature reviews and assessment of existing work There is a strong need to start to address concrete issues, may be few but concrete The starting point for all SGs should be the Guidance doc. Therein open issues and research aspects to be tackled in connection to AQD are clearly stated!

SG discussions guidelines 2/3 The SGs cover nicely all aspects connected with grey areas in the AQD: Refer to the document, Extract open issues, Prioritize them, Define the available resources, Produce a defined work plan for the next 12 months We have to aim at a: consistent, coordinated and concrete product readily available to WG1/DG-ENV for implementation pre–operational concept, procedure, methodology, indication, guideline, tool that clarifies the grey areas as much as possible.

Have we identified specific grey areas? SG discussions guidelines 3/3 Always consider the following questions: Are we contributing to specific issues addressed in the Guidance document? Have we identified specific grey areas? Have we identified the way to proceed to clarify them? Are the issues tackled connected in some ways with those of other SGs?
