OpenAQ: Exploring Open Air Quality Data and Global Monitoring
USEFUL SOURCES · OFFICIAL TECHNICAL RESOURCE · OCTOBER 2026
OpenAQ helps make publicly available air quality measurements easier to discover and use for analysis, research and public communication.
What Is This Resource?
The platform supports access to air quality observations from participating monitoring networks. Its data tools help researchers and developers explore observations by location, time and pollutant, subject to each dataset’s availability and characteristics.
What You Can Find There
- Publicly accessible air quality measurement data and supporting metadata.
- Monitoring location and pollutant information.
- Tools and documentation for working with open datasets.
- Starting points for analysis, visualization and data-driven research.
How to Use It in Practice
Choose a pollutant, geographic area and time period, then inspect the measurement units, source, observation frequency and completeness. Compare like with like: daily means are not interchangeable with real-time samples, and missing observations can distort trends.
Why It Matters for AirAlign
A valuable reference for AirAlign’s longer-term dashboards, APIs and data analytics interests. It can also help illustrate the difference between a published open dataset and readings from an individual consumer sensor.
Open data does not mean every location or pollutant is covered, or that every dataset has identical quality controls. Observe API terms, licensing, attribution and usage limits before building an application.
