Snippet: To measure air quality, we use the EPA Air Quality Index (AQI), which measures air quality derived from ground monitors (62) . The AQI captures pollution from particulate matter (PM2.5), sulfur dioxide (SO2), carbon monoxide (CO), nitrogen dioxide (NO2) and ozone (O3). Further details on AQI calculation are provided by the EPA (63). We use the daily, county level, pre-aggregated data and further aggregate up to the county-by-month level. For miss.....
Document: To measure air quality, we use the EPA Air Quality Index (AQI), which measures air quality derived from ground monitors (62) . The AQI captures pollution from particulate matter (PM2.5), sulfur dioxide (SO2), carbon monoxide (CO), nitrogen dioxide (NO2) and ozone (O3). Further details on AQI calculation are provided by the EPA (63). We use the daily, county level, pre-aggregated data and further aggregate up to the county-by-month level. For missing county-months, we take the average value of the adjacent counties in the same month. We use the average value of the AQI within a month as well as the number of days with air at least "unhealthy for sensitive groups" according to the EPA (AQI≥100). We winsorize the AQI at the top and bottom 1% for the main analysis and show robust results without winsorization. For our analysis, we take the one month lagged AQI to identify exposure to air pollution before influenza diagnosis and not afterwards.
