Highlights

The air quality monitor at Pinnacle Peak Club House in north Scottsdale recorded ozone at 75.0 parts per billion at 9 p.m. Thursday, crossing the AirNow threshold designated Unhealthy for Sensitive Groups, according to the EPA AirNow public hourly aggregate reported by the Maricopa County Air Quality Department.

The reading was logged at AQS site ID 040132005, the Pinnacle Peak Club House station. The Unhealthy for Sensitive Groups designation applies when ozone concentrations reach levels that may affect people with respiratory or cardiovascular conditions, children, and older adults, according to ADEQ's Phoenix forecast page, which notes that vulnerable populations include those with asthma, bronchitis, heart or lung disease, and adults exercising outdoors.

Real-time conditions and any active alerts for the Phoenix metro are available through AirNow's Phoenix-area page. Updated hourly readings for the Pinnacle Peak Club House station are also tracked at air-quality.com.
