FAIRMODE - Forum for Air Quality Modeling

FAIRMODE brings together air quality modelers and users to promote and support the harmonized use of models by EU Member States to support the European Air Quality Directives.

Planning (Working Group 5)

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

Guidance

Leaders: Stijn Janssen (VITO), Joana Soares (NILU)

FAIRMODE is the Forum for Air Quality Modeling created for exchanging experience and results from air quality modeling in the context of the Air Quality Directives (AQD) and for promoting the use of modeling...

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.

Tools and datasets

The Delta Tool software is an IDL-based model evaluation tool developed within the framework of FAIRMODE for benchmarking Ambient Air Quality Directive (AAQD) modelling applications.
SHERPA (Screening for High Emission Reduction Potential on Air) is a Python tool, which allows for a rapid exploration of potential air quality improvements resulting from national/regional/local emission...
