Air Quality forecast in South America
NOAA NEMS GFS Aerosol Component

Show forecast animation for :
PM2.5

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.

Future Improvements

We need your help

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!

    About the Air Quality and Pollution Measurement:

    About the Air Quality Levels

    AQI Air Pollution Level Health Implications Cautionary Statement (for PM2.5)
    0 - 50 Good Air quality is considered satisfactory, and air pollution poses little or no risk None
    51 -100 Moderate 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. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
    101-150 Unhealthy for Sensitive Groups Members of sensitive groups may experience health effects. The general public is not likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
    151-200 Unhealthy Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion
    201-300 Very Unhealthy Health warnings of emergency conditions. The entire population is more likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.
    300+ Hazardous Health alert: everyone may experience more serious health effects Everyone should avoid all outdoor exertion
