Air Quality API
Access high-resolution global air quality data built from model guidance and monitoring stations. Products are bias-corrected and gap-filled to support current conditions, forecast operations, and historical analysis.
Obtain data for the 6 major surface pollutants - PM 2.5, PM 10, CO, SO2, NO2, and O3. As well as air quality index score (AQI) as well as pollen levels (USA and EU only).
Advantages
High Spatial Resolution: Air quality products are delivered at high spatial resolution with blended model and station inputs.
High Precision and Accuracy: Statistical and machine-learning methods are used to correct bias and improve operational quality.
Continuously Updated Forecasts: Forecast products are refreshed as conditions change, rather than only once per model run.
Historical + Current Continuity: Hourly historical and current air quality products use aligned fields for consistent operational analysis.
Available APIs
- Current Air Quality API: current pollutant concentrations and AQI.
- Air Quality Forecast API: hourly forecast guidance out to 72 hours for global locations.
- Historical Air Quality API: hourly historical air quality data for retrospective analysis and validation.
