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 are designed for consistent operational workflows.
Available APIs
- Current Air Quality API: current pollutant concentrations and AQI, with pollen fields where available.
- 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.
