On the Wisconsin DNR Air Quality website, I want to understand what the 'Unhealthy for Sensitive Groups' air quality level means for 8-hour Ozone and 24-hour PM2.5 concentrations. Also, clarify if the real-time air quality data displayed on the 'Air Quality Index (AQI)' page is considered official for regulatory purposes.
Navigate to the 'Air Quality Index (AQI)' page. Locate the table titled 'How AQI ranges correspond to ozone and PM 2.5 concentrations'. Identify the 8-hr Ozone (ppb) and 24-hr PM2.5 (ug/m3) ranges for the 'Unhealthy for Sensitive Groups' AQI level. On the same page, locate the section discussing 'AQI calculations for the current day' and 'NowCast AQI calculations'. Determine if the real-time data is considered official for regulatory purposes based on the provided disclaimers. Synthesize the collected information into a concise answer.
State the 8-hr Ozone (ppb) range for 'Unhealthy for Sensitive Groups' as 71-85. State the 24-hr PM2.5 (ug/m3) range for 'Unhealthy for Sensitive Groups' as 35.5 to 55.4. State that the real-time data presented on the webpage (using NowCast AQI) is not used for regulatory purposes and should be considered unofficial.
