Thank you for your post, but please note:

Windy does not create any forecast data but instead only visualises forecast and actual data received from various third party providers.

Please see the following thread regarding PM2.5 data,especially in relation to the current situation in Australia:https://community.windy.com/topic/10900/air-quality-pm2-5-data-and-forecasts

@jmh2002 said in Air Quality PM2.5 Data and Forecasts:

The forecast visualisations are based on the forecast data received. So Windy has no part in the reliability of this.

If the actual conditions have changed relative to the previous forecast then the visualisation of this data will of course not reflect this.

PM2.5 is forecast data from https://www.copernicus.eu/en ( https://community.windy.com/topic/7924/cams-signs-partnership-with-weather-application-windy ) and it is updated every 24 hours., It is not actual data and with rapidly changing conditions such as the fires in Australia this may result in some differences..

For all layers you can check the source of the data by clicking the clock/time/info icon in the bottom right hand corner.

Thank you for your post, but please note that the Feedback and Suggestions section is for issues associated with Windy, not for weather forecast differences.

Windy does not create any forecast data but instead only visualises forecast and actual data received from various third party providers.
Windy therefore has NO control over the forecast or actual data provided.

@Gkikas-LGPZ Well investigated my friend :)

Bug reporting is for technical issues associated with Windy, not forecast differences.

One thing I would love is for air quality to be added to the forecast information for a place. At the moment you can manipulate the map to see forecast air quality everywhere at one point In time, but you cannot see the forecast over time for one place. In Australia we now need to plan our lives around air quality.

This might be a helpful addition. However also please note that you can see the various air quality forecasts over time for one place by using the time slider in the bottom left hand corner.

I am requoting the above to again remind users that Windy has NO control over the forecast or actual data provided. Windy only visualises this data.

For improvements to the forecasts please feel free to contact the model providers such as https://www.copernicus.eu/en , ECMWF, GFS, etc, and update them with your concerns.

Although normally forecast anomolies can be explained or understood in many different ways, the simplest of which is that it is a Forecast (ie: an advance prediction) - it is not actual live data.

Thank you for your understanding.
