Description

The aim of this WG is to support the use of modelling approaches for air quality planning purposes. It includes:

• Support to local, regional and national authorities in designing efficient and coherent measures,
• Exchange of good practices to harmonise the reporting of air quality plans and ensure comparability,
• The development of QA/QC methods to assess the quality of models when used for planning purposes.

The WG5 activities will focus on:

1. Using models in support to the AQ planning process. What are the main obstacles, both from a technical and governance perspective?
2. Assessing the sensitivity and robustness of model responses to emission reductions
3. Providing recommendations on the combined use of models and observations for planning purposes
4. Supporting the reporting of plans and air quality measures through a common template
5. Evaluating consequences for e-reporting of planning data
6. Providing overall support to model users (SHERPA, air quality models…) in their planning activities (measures, emission and model scenarios)

Currently we are performing a "bias projection" exercise, to improve the way in which air quality models are "bias corrected" both on basecase and scenarios. The description of the "phase 1" of this exercise can be found here. The description of the "phase 2" of this exercise can be found here.
