Tracking Air Quality

Air Quality Index

The Air Quality Index (AQI) is a helpful method to easily track the air quality around you. This index is used by local governments to inform the general public about the relative air quality for a city or large metropolitan areas. The air quality index used differs from country to country.

The United States Environmental Protection Agency (EPA) has developed an Air Quality Index that is used to report air quality. This AQI is divided into six categories indicating increasing levels of health concern. An AQI value over 300 represents hazardous air quality and below 50 the air quality is good.

Many factors influence the level of air pollution. Some of these factors include:

  • Wind
  • Traffic
  • Industry
  • Fires

Several different websites keep track of the Air Pollution Index (AQI) and presents the information on maps. For example https://aqicn.org/ has information on  most cities in the world. Below is the real-time map of air pollution in Bangkok.

AirVisual App

A good method to know the macro-environment air quality in your city is through the AirVisual App. The app can automatically locate the city you are in, and show you the relevant air quality information. You can choose other cities or areas as needed, and even see map views of all the AQI readings sources.

The screenshots below show Chiang Mai in Thailand. You can also set notifications or alerts as needed for the current air quality in your city.  This can then give you a heads up as to what you may expect before you go out to work or play.

Download the app here and get started.
