City Forecast

Note: The colors used for PM2.5, PM10 and Ozone (O3) are based on the US EPA standard. The colors used for Nitrogen Dioxide (NO2), Sulphure Dioxide (SO2) and Carbon Monoxyde (CO) are based on an arbitrary color standard which best matches the concentration range. It does not have any relation with the AQI breakpoints, as in most cases, the AQI for those 3 gases is most often below 50.

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?

Sobre a medição da aualidade do ar e poluição

Sobre os níveis de qualidade do ar

- Valores do índice de qualidade do ar (IQA).Níveis de preocupação com a saúde
0 - 50 Boa 0-50: Boa - A qualidade do ar é considerada satisfatória, a poluição do ar representa pouco ou nenhum risco
51 -100 Moderado A Qualidade do ar é aceitável; no entanto, para alguns poluentes pode haver uma preocupação de saúde moderada para um número muito pequeno de pessoas que são especialmente sensíveis à poluição atmosférica.
101-150 Insalubre para grupos sensíveis Membros de grupos sensíveis podem experimentar efeitos na a saúde. O público em geral não é susceptível de ser afetado.
151-200 Insalubre 150-200: Insalubre - Todo mundo pode começar a sentir os efeitos na saúde; membros de grupos sensíveis podem apresentar efeitos mais sérios de saúde.
201-300 Muito Insalubre Advertências relativas à saúde das condições de emergência. Toda a população tende a ser afetada.
300+ Perigoso 300+: Perigoso - alerta de saúde: todos podem experimentar efeitos mais graves para a saúde
