Model Comparison

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.

Forecast Analysis

How accurate are the forecasts? Check the correlation graphs below for PM2.5, 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 PM2.5 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).

Air Quality Forecasts Models

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.


Future Improvements

Do you like our forecast model analysis tool called GOA?

Our objective is to create the best world air quality ensemble forecast - which can maximize the forecast accuracy and efficiency for any place on earth (and especially for the 600+ cities covered on the aqicn.org).

We are now looking at extending this GOA tool with many more models and features such as Artificial Intelligence (AI) based model correction, real-time deterministic statistic analysis, or automatic emission correction.

We are not in favor of replacing deterministic models with AI models, but rather to use the AI to complement the models and create the best ensemble model using deep learning solutions.

Do you link this idea? Do you want to contribute?

Forecast Model Sources

The above prediction is based on composite meta model, computed using several Air Quality Forecasting Systems (AQFS): The above map is based on the PM2.5 surface level modeling, and colors are following the US EPA AQI standard.

À propos de la qualité et de la mesure de la pollution atmosphérique:

A propos des niveaux de qualité de l'air

IQANiveau 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 Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
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.
