Contacting the World Air Quality Index team

The World Air Quality Index project is a social enterprise project started in 2007. Its mission is to promote Air Pollution awareness and provide a unified Air Quality information for the whole world.

The project is proving a transparent Air Quality information for more than 70 countries, covering more than 9000 stations in 600 major cities, via those two websites: aqicn.org and waqi.info.
The base team is located in Beijing, China and composed of several contributors in the domain Environmental Sciences, System Engineering, Data Science and Visualization, Machine Learning as well as Visual Design.

The team has been expanding worldwide, and several contributors, located in Singapore, India, Australia and USA are now also supporting the project.

Common question & answers

  1. Air Quality Data sources: All the Air Quality data seen on World Air Quality Index are the official data from each country respective Environmental Protection Agency (EPA). Data from each EPAs is measured using professional monitoring equipment. The full EPA source list used in World Air Quality Index is available from sources page.
  2. Seeing different readings from other websites: This is most likely normal, and due to the fact that different websites use different AQI scales present the data. At World Air Quality Index, we are using the US EPA scale, while other website might use different scales. Check this article for more information.
  3. I want to monitor the air quality in my area: As high-end professional stations can be really expensive (more than $10K per stations), the World Air Quality Index project / Earth Sensing Labs has designed specialy optimized and affordable monitoring stations costing as low as $200. Please check the GAIA air quality monitoring station product page.
  4. I want to add a new station on the map: Provided your monitoring station is qualified (for instance if it is using BAM, TOEM or GAIA technology), then adding a new station on the map is not only simple and straightforward but also completely free. Please refer to this page for the full explanation
  5. Data quality & real-time validation: The data published on World Air Quality Index is real-time and therefore unvalidated at the time of publication. In order to strengthen the quality, a set of real-time AI algorithms are used to detect abnormal data conditions (sparks, low reporting, etc.) and automatically 'disable' data reported from defective stations.
  6. Historical data access: We are currently investigating with several international institutions (WHO, UN, GEO) the possibility to setup a framework for accessing the historical Air Quality data. If you are from an international institution, organization or university and want to join this effort, then check our data platform page.
  7. API (Application Programing interface): The World Air Quality Index project is offering a free API for maps, tiles and programatic JSON access. Check the API page for more information.
  8. Contributing to the World Air Quality Index project: The project is always looking for more hands to support the activities: For instance, to write articles, to improve our applications, to create new data visualization, to improve the air quality forecast or to translate the website and app to news languages. Check the contribute page for more info.
  9. Fundings: The World Air Quality Index project is independent from any governement and any "profit" corporation. It has so far not received any fundings from any public entities. However, in order to keep the highlest level of integrity for the health related information published on aqicn.org and waqi.info, we are now actively working on seting-up funding links from the UN, the WHO, the WMO, as well several of the global EPAs as well as the major NGOs.
  10. Why chosing the U.S. EPA index to harmonize the data? This is mostly for historcal reason: When we started in 2007, there was not so many alternative, and the US EPA was actually quite proactive at promoting the idea of clean air, so the choice was natural. Some alternatives, such as the European “Common Air Quality Index” could also have been a good option, but the EEA failed to promote their standard. This won't be a problem for long anyways, since we are now working on a improvement which will allow users to select any scale they want among a list of more than 80 scales!
  11. How many cities do you currently provide air quality data for and is the info available on your app in each of them? We are providing the data for 9000 stations worldwide ~ that’s around 600 major cities in 70 countries. The info is available in the app for each of them, but not all of the cities have the “full” set of pollutant monitoring (e.g. PM2.5, PM10, Ozone, NO2, SO2, CO). For example, some only have PM10 or a composite AQI. We are also continuously increasing the coverage, targeting to get 10 to 20% more stations every year. The full list of cities and stations is available from this page.
  12. Media kit? Our public media kit is available from the media kit page.
Any other question, please check the Frequently Asked Question page.

About the Air Quality and Pollution Measurement:

About the Air Quality Levels

AQIAir Pollution LevelHealth ImplicationsCautionary Statement (for PM2.5)
0 - 50 Good Air quality is considered satisfactory, and air pollution poses little or no risk None
51 -100 Moderate Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
101-150 Unhealthy for Sensitive Groups Members of sensitive groups may experience health effects. The general public is not likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
151-200 Unhealthy Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion
201-300 Very Unhealthy Health warnings of emergency conditions. The entire population is more likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.
300+ Hazardous Health alert: everyone may experience more serious health effects Everyone should avoid all outdoor exertion
