How Aeriqo Works
Transparency is important when it comes to health-related data. Here's exactly how we collect, process, and present air quality information.
Data Sources
Government Monitoring Stations
Where available, we prioritize official government air quality data. These monitoring networks provide verified measurements from calibrated professional equipment.
- Hourly measurements from official stations
- Calibrated professional equipment
- Verified government data sources
Global Coverage Providers
For locations without nearby government stations, we use established air quality data providers that combine satellite data, atmospheric modeling, and ground station measurements for global coverage.
- Worldwide coverage for any location
- Grid-based atmospheric modeling
- Multiple data source aggregation
For detailed information about specific data sources and attribution, see our Data Sources page.
Update Frequency
Air quality data providers typically refresh their measurements hourly. When you check air quality for a specific location, you're seeing the most recent data available from monitoring stations and atmospheric models. The app dashboard provides fresh data whenever you refresh or navigate.
AQI Calculation
We calculate the Air Quality Index using the EPA (United States Environmental Protection Agency) methodology:
- Retrieve concentration values for each pollutant (PM2.5, PM10, O3, NO2, SO2, CO)
- Convert each pollutant concentration to a sub-index using EPA breakpoint tables
- The overall AQI is the highest sub-index among all pollutants
- For routes, we check air quality at points along your path, show you what each segment looks like, and give you the average for the whole route
The dominant pollutant (the one driving the AQI) is displayed when available to help you understand which pollutant is of primary concern.
Limitations & Disclaimer
- Not medical advice: Aeriqo provides general guidance based on publicly available data. It should not replace medical advice, especially for individuals with respiratory or cardiovascular conditions.
- Monitoring station coverage: Air quality can vary significantly over short distances. Our data represents regional conditions, not necessarily your exact location.
- Data accuracy: We rely on third-party data sources. While we use official government data where available, we cannot guarantee accuracy or completeness.
- Delayed updates: There may be delays between actual conditions and reported values due to data processing and transmission.
