What Is The Air Quality Index And What Does It Mean?
The Air Quality Index (AQI) is an indicator of outdoor air quality in Ontario. Using a network of 40 state-of-the art air monitoring stations, the Ministry of the Environment (MOE) takes real-time air quality data from the monitoring sites and produces AQI readings for each location. The City of Windsor is currently served by two AQI monitoring stations, one located in west Windsor and one located downtown.
The Air Quality Index (AQI) is based on hourly pollutant measurements of the most common air pollutants: sulphur dioxide (SO2), ozone (O3), nitrogen dioxide (NO2), carbon monoxide (CO) and fine particulate matter (PM2.5). At the end of each hour, the concentration of each pollutant that the AQI station monitors is converted into a number ranging from zero upwards, using a common scale, or index (like a ruler for measurement). The pollutant with the highest number at a given hour becomes the AQI reading. The lower the AQI reading, the cleaner the air.
of 15 or below: the air quality is considered very good.
- AQI between 16 and 32: the air quality is considered relatively good.
- AQI between 32 and 49: the air quality is considered moderate. There may be some adverse effects on very sensitive people.
- AQI between 50 and 99: the air quality is considered poor. Some short-term adverse effects on people or animals may be expected, or may cause significant damage to vegetation and property.
- AQI of 100 or more: the air quality is considered very poor. This may cause adverse effects on a large proportion of people.
The MOE publishes the air quality index daily on their Air Quality Ontario website . This website also reports up-to-date hourly data. A new mapping feature allows the viewer to compare data across Ontario.
