A number of stations have lost communication due to a technical issue.
Apologies, forecast maps are not currently available. We are working to resolve this issue.

Explanation of Monitoring Stations Map Above

The map above updates regularly with the most up-to-date calculated Air Quality Index for Health (AQIH) for each station.

If a station is grey , there may be an instrument or communication issue associated with it or it may be undergoing planned maintenance/upgrade.

If a station is blue , it means that it is a non-automated station and data will only be available following laboratory analysis. (There are only 2 of these stations.)

The diamond-shaped markers on the map relate to the Local Monitoring Network. These give an indication of air quality. The tab to turn the Local Network layer on/off is in the top right corner of the map.

Explanation of Forecast Maps Above

The Air Quality Forecast Maps predict the daily air quality based on the Air Quality Index for Health (AQIH) for up to 3 days (today, tomorrow and the day after tomorrow).

Daily concentrations of particulate matter, nitrogen dioxide and ozone presented correspond to a point on the AQIH scale. The AQIH ranks the amount of pollutant in the air on a scale from 1 to 10, with 1 (light green) being the cleanest air and 10 (purple) being the most polluted. More information on the AQIH is available here.

The AQIH index for each pollutant is worked out separately, and the overall AQIH for each grid in the map represents the highest point for all pollutants assessed.

Use the dropdown menu to navigate to each map.

These maps are updated twice daily, once in the morning and once in the evening. Forecasts for the day after tomorrow are only available after the morning and evening updates. Maps should be updated by 9:30 am and 7:30 pm each day.

The above maps give everyone in Ireland air quality information to plan their outdoor activities in order to reduce potential exposure to poor air quality and to protect their health.

The forecast also helps to increase awareness of air quality issues and will help us all to take steps to reduce air pollution in Ireland.
