Tomorrow.io’s platform offers comprehensive air quality monitoring through a range of environmental parameters. These metrics help organizations assess health risks, meet compliance standards, and plan accordingly in response to changing air conditions.
🔒 This is a premium feature. To request access or learn more, please contact your Tomorrow.io Account Team or sales@tomorrow.io.
Key Parameters
| Parameter | Description |
|---|---|
| AQI (EPA) | Air Quality Index based on U.S. Environmental Protection Agency (EPA) standards. Reflects health implications of prolonged exposure to air pollutants. |
| AQI (China) | Air Quality Index according to China’s Ministry of Environmental Protection (MEP) guidelines. Useful for regions within or near China. |
| Particulate Matter PM2.5 | Concentration of airborne particles with diameters less than 2.5 micrometers. These fine particles can enter deep into the lungs and bloodstream. |
| Particulate Matter PM10 | Measures larger airborne particles with diameters under 10 micrometers. These pose respiratory and cardiovascular risks. |
Forecasted Pollutant Levels
In addition to AQI values, Tomorrow.io provides forecasts for individual pollutants that significantly impact air quality:
- Nitrogen Dioxide (NO₂) – Commonly produced by vehicle emissions and industrial sources
- Ozone (O₃) – Created by chemical reactions between sunlight and pollutants like NOx
- Sulfur Dioxide (SO₂) – Emitted from burning fossil fuels, especially in power generation
- Carbon Monoxide (CO) – A colorless, odorless gas harmful when inhaled; largely from vehicles and equipment
