City Forecast

This section is experimental. It provides the comparison for the prediction for several individual forecast models

For a full list of all Air Quality Forecast models beeing analysed, check the Forecast Models page.

How accurate are the forecasts? Check the correlation graphs below for PM_2.5, PM₁₀ and Ozone for the past 30 days. (Note that all values are based on the AQI, and that a maximum threshold of 300 is used).

Past month PM_2.5 AQI short-term forecast analysis.
In the above graph, the forecast is data is the forecast one day in advance (i.e. the forecast computed today for tomorrow).

There are many forecast models, for different regions of the globe - below are few of them. Just click on any of them to see the animated map for the given model.

For a full list of all forecast model and polutants, check the forecast/model page.

Please note that all above analysis are done on the World Air Quality Index (WAQI) project own budget.
We did not receive any subsidies from any of the intuitions publishing Air Quality forecast models.

Cooperation needed!

Help is needed for keeping the world-wide Air Quality forecast model inventory up-to-date.

Do you know any model not listed below but for which gridded data is available?

Do you know better accuracy analysis solutions which should be used here?

Have you done a similar research and you would like to publish it here?

If yes, drop us a message from the contribute page and we will contact you asap!

The above prediction is based on composite meta model, computed using several Air Quality Forecasting Systems (AQFS):

The Spectral Radiation-Transport Model for Aerosol Species (Sprintars) model from Kyushu University.
The China National Air Quality forecast by Zhejiang Experts in Experimental Sciences (PM2.5科学实验专家小组).
The Air Korea Air Quality forecast, by the Korean Integrated Air Quality forecast center(대기질 통합예보센터).
The Copernicus Atmosphere Monitoring Service (CAMS) near-realtime surface ensemble forecast , by the ECMWF.
The System for Integrated modeLling of Atmospheric coMposition (SILAM) by the Finnish Meteorological Institute (FMI).
The Max Planck Institut fur Meteorologie (MPIM) model.
The Ozone Air Quality Model (AQM) by the NOAA/NCEP.
The Regional Air Quality Deterministic Prediction System (RAQDPS) model from the Government of Canada.
The irCELine (Belgian Interregional Environment Agency) for the Belgian Regions.
The LCSQA (Laboratoire Central de Surveillance de la Qualité de l’Air) for France.
The RIVM (Rijksinstituut voor Volksgezondheid en Milieu) for the Netherlands.
The SILAM (System for Integrated modeLling of Atmospheric coMposition) for Northen Europe.
The EURAD (EURopean Air Pollution Dispersion) for Central Europe.

The above map is based on the PM_2.5 surface level modeling, and colors are following the US EPA AQI standard.

À propos des niveaux de qualité de l'air

IQA	Niveau de pollution de l'air	Impact sur la santé
0 - 50	Bon	La qualité de l'air est jugée satisfaisante, et la pollution de l'air pose peu ou pas de risque.
51 -100	Modéré	La qualité de l'air est acceptable. Cependant, pour certains polluants, il peut y avoir un risque sur la santé pour un très petit nombre de personnes inhabituellement sensibles à la pollution atmosphérique.
101-150	Mauvais pour les groupes sensibles	La qualité de l'air est acceptable; Cependant, pour certains polluants, il peut y avoir un problème de santé modérée pour un très petit nombre de personnes qui sont particulièrement sensibles à la pollution de l'air.
151-200	Mauvais	Tout le monde peut commencer à ressentir des effets sur la santé; les membres des groupes sensibles peuvent ressentir des effets de santé plus graves.
201-300	Très mauvais	Avertissements de santé de conditions d'urgence. Toute la population est plus susceptible d'être affecté.
300+	Dangereux	Alerte de santé: tout le monde peut ressentir des effets de santé plus graves.
