Station place card
Station place cards display data from official government air quality monitoring stations. These stations are operated by environmental agencies and provide reference-grade measurements that complement AirScape's sensor network.
Difference from AirScape sensors
| Feature | AirScape Sensor | Government Station |
|---|---|---|
| Location | Street level | Often elevated or in specific zones |
| Update frequency | Every few minutes | Typically hourly |
| Coverage | Dense urban networks | Sparse, strategic placement |
| Pollutants measured | PM2.5, PM10, NO2, O3 | May include additional pollutants |
What you'll see
Station place cards show:
- Official AQI reading: Government-reported Air Quality Index
- Available pollutants: All pollutants measured at this station
- Station name: Official designation from the environmental agency
- Data source: Which government agency operates the station
- Update time: When the last reading was reported
Why include stations?
Government monitoring stations provide:
- Reference data: Calibration benchmarks for sensor accuracy
- Regulatory compliance: Official readings used for air quality standards
- Extended coverage: Data in areas without AirScape sensors
- Additional pollutants: Some stations measure pollutants our sensors don't
Using station data
Station data is useful for:
- Comparing with nearby AirScape sensor readings
- Understanding official air quality assessments
- Viewing data in areas without dense sensor coverage
- Accessing historical records maintained by government agencies
