Verification of Regional Services

Validation Reports

The regional modelling systems are being validated on a 3-monthly basis. The validation reports are available here:

Quick-look verification pages

The verification of the MACC-II Regional Air Quality services over Europe is based on comparisons with in-situ surface observations of the following air pollutants: ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide and PM10 aerosols. These hourly observational data are delivered to the MACC-II project close to real-time. They are preliminary and not validated and can therefore not be used for checking compliance with air quality regulations or for any purpose other than the evaluation of MACC-II Regional Air Quality products. Detailed information can be obtained from the data owners.

Forecast verfication against in-situ observations

Maps of the forecasts of surface pollutants (ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide and PM10 aerosols) produced by each of the 7 individual models or from the ensemble on a 3-hourly basis, overlaid with in-situ observations as coloured dots. Available for the past 30 days.

Analysis verfication against in-situ observations

Maps of the ozone analysis at the surface produced by each of the 7 individual models or from the ensemble on a 3-hourly basis, overlaid with in-situ observations as coloured dots. Available for the past 30 days.

Forecast versus analysis verification

Maps of the daily maximum at the surface for the different pollutants (ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide and PM10 aerosols) from the analysis together with the forecasts for Day 0, Day 1, Day 2 and Day 3. Available for each of the 7 individual models and the ensemble for the past 30 days.

Mean forecast scores

Statistical indicators (mean bias, normalized modified mean bias, root mean square error, fractional gross error and correlation) averaged over the past week or over the past 3 months displayed over the 0 to 96h forecast range for the 7 individual models and the ensemble. Available for the past 30 days.

Time series of forecast scores

Time series of the statistical indicators (mean bias, normalized modified mean bias, root mean square error, fractional gross error and correlation) for the past week or past 3 months of the forecasts of the 7 individual models and the ensemble at 03UTC or 15 UTC. Available for the past 30 days.

Taylor diagrams

Taylor diagrams of the 7 individual models and the ensemble based on statistical indicators (standard deviation and correlation) of the 0-24h forecast averaged over a week or 3 months for the different pollutants (ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide and PM10 aerosols).
