Air Data Report
Every year, the Air Data Report charts air quality monitoring data collected at 30 monitors for criteria pollutants. The report is only available after all data has gone through quality control, generally the summer following the year of sampling.
Staff provides daily Air Quality Index (AQI) forecasts for 3 metropolitan areas. To view the actual AQI values of previous dates, view these charts.
