Quality assurance, quality check and fitness for purpose of AQ assessment modelling applications (Working Group 2)

While this Working Group 2 activities have so far focused on developing a methodology to benchmark model performance (Modelling Quality Objective (MQO), QA/QC protocol), future activities will focus on regular inter-comparison exercises based on the Composite Mapping platform and use of the MQO indicators.

FAIRMODE guidance document on modelling quality objectives and benchmarking - Version 3.3

The development of the procedure for air quality model benchmarking in the context of the Air Quality Directive 2008/50/EC (AQD) has been an on-going activity in the context of the FAIRMODE community. A central...

Description

While this working group activities have so far focused on developing a methodology to benchmark model performance (Modelling Quality Objective (MQO), QA/QC protocol), future activities will focus on regular inter-comparison exercises based on the Composite Mapping platform and use of the MQO indicators:

  1. Regular inter-comparisons and targeted analysis of key reported assessment data (modelling air concentrations & emissions aggregated data)
    • Targeted analysis of the Modelling Quality Indicator (MQI) across Europe (based on the comparison of on-the-fly and reported MQI)
    • Targeted study of the underlying emission data (Emission Dashboard – link to WG7)
    • Testing usability and usefulness of modelling metadata
    • Consequences for e-reporting of modelling data
  2. Guidance on model application, documentation and validation
    • Update of the 2011 FAIRMODE guide on model application
    • Support to AAQD guidance on model use
    • Support to CEN WG43 (MQO) on the implementation of MQI
