कास्ट वायु गुणवत्ता सूचकांक (AQI) खोज शहर से बंद आधारित उपयोगकर्ता स्थान या घटना

Clean Air Cast only serves the purpose of better human health by informing air quality index(AQI) based off user current location.

Users can recognize current AQI state by icons and colors. Also, users can look up other cities AQI by searching city name or map view.

The AQI can increase due to an increase of air emissions (for example, during rush hour traffic or when there is an upwind forest fire) or from a lack of dilution of air pollutants. Stagnant air, often caused by an anticyclone, temperature inversion, or low wind speeds lets air pollution remain in a local area, leading to high concentrations of pollutants, chemical reactions between air contaminants and hazy conditions.

On a day when the AQI is predicted to be elevated due to fine particle pollution, an agency or public health organization might:

- advise sensitive groups, such as the elderly, children, and those with respiratory or cardiovascular problems to avoid outdoor exertion.

- declare an "action day" to encourage voluntary measures to reduce air emissions, such as using public transportation.

- recommend the use of masks to keep fine particles from entering the lungs
