Air Quality Index Summary Report

Each row of the AQI Summary Report lists summary values for one year for one county or metropolitan statistical area (MSA). The summary values include both qualitative measures (days of the year having "good" air quality, for example) and descriptive statistics (median AQI value, for example). Each row also includes a link to a chart of the daily AQI values summarized in that row.
