Air Quality at HBurg-WX.net
| PM2.5: | 49.0 µg/m³ |
| Real-Time AQI: | 134.0 |
| Condition: | UNHEALTHY FOR SENSITIVE GROUPS |
Data shown above are collected by HBurg-WX.net with an Ambient Weather Wireless PM25 Air Quality Sensor. PM2.5 refers to particulate matter that is 2.5 micrometers in diameter or smaller, which can be inhaled deeply into the lungs and may enter the bloodstream. Common sources include vehicle exhaust, industrial emissions, and smoke from fires.
Virginia DEQ Air Quality — Harrisonburg VDOT
Virginia DEQ data are preliminary real-time observations and may not yet have completed quality-assurance review.
Current Pollutant Measurements
| Pollutant | Concentration | AQI | Category |
|---|---|---|---|
| PM2.5 Fine particles | 4.6 µg/m³ | 26 | Good |
| PM10 Coarse particles | 11 µg/m³ | 10 | Good |
| Ozone Ozone | 5 ppb | 5 | Good |
| NO2 Nitrogen dioxide | 15 ppb | 14 | Good |
| SO2 Sulfur dioxide | 0.2 ppb | 0 | Good |
Detailed pollutant concentrations are supplied by EPA AirNow using observations from the Virginia DEQ monitoring network. The concentration shown is the latest raw hourly instrument measurement when available; otherwise the AirNow-reported concentration is used.
The HBurg-WX sensor and Virginia DEQ monitor are different instruments at different locations, so their PM2.5 concentrations and AQI values should not be expected to match exactly.
