AQI coloured map and/or data not available!

The air quality database to produce the air quality indices undergoes maintenance at regular intervals. During these periods the AQI coloured map and/or air quality indices will be temporarily unavailable.

For reasons beyond our control, it is also possible that the AQI coloured map and/or air quality indices may occasionally be unavailable. We will remedy these situations as quickly as possible whenever they arise.

Notice: Although the IQA coloured map is not available for the time being, you may still be able to get the air quality indices and/or the graphic showing the AQI changes for the current and previous day: click on the region or the community of your choice to see them.
