Air Data Report
Every year, the Air Data Report charts air quality monitoring data collected at numerous 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. Data for previous years are available upon request. Please contact the Monitoring section managers at 405-702-4100.
Staff provides daily Air Quality Index (AQI) forecasts for 3 metropolitan areas. To view the actual AQI values of previous dates, view these charts.
