Kontakt zum World Air Quality 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 80 countries, covering more than 10,000 stations in 800 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.
The project is constantly looking for more contributors, and it has now received support from citizens from more than 98 countries:

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.

Über Messungen zur Luftqualität und Verschmutzung

Über die Luftqualitätsstufen

- Werte zur Luftqualität (AQI)Stufen zur Bewertung der Gesundheitsgefährdung
0 - 50 Gut Die Qualität der Luft gilt als zufriedenstellend und die Luftverschmutzung stellt ein geringes oder kein Risiko dar
51 -100 Moderat Die Luftqualität ist insgesamt akzeptabel. Bei manchen Schadstoffe besteht jedoch eventuell eine geringe Gesundheitsgefahr für einen sehr kleinen Personenkreis, der sehr empfindlich auf Luftverschmutzung ist.
101-150 Ungesund für empfindliche Personengruppen Bei Mitgliedern von empfindlichen Personengruppen können gesundheitliche Auswirkungen auftreten. Die allgemeine Öffentlichkeit ist wahrscheinlich nicht betroffen.
151-200 Ungesund Erste gesundheitliche Auswirkungen können sich bei allen Personen einstellen. Bei empfindlichen Personengruppen können ernstere gesundheitliche Auswirkungen auftreten.
201-300 Sehr ungesund Gesundheitswarnung aufgrund einer Notfallsituation. Die gesamte Bevölkerung ist voraussichtlich betroffen.
300+ Gefährlich Gesundheitsalarm: Jeder muss mit dem Auftreten ernsterer Gesundheitsschäden rechnen

Um mehr zur Luftqualität und -verschmutzung zu erfahren, gehen Sie auf die Seite wikipedia Luftqualität Thema oder den AIRNow Leitfaden für Luftqualität und Ihre Gesundheit .

Sehr nützliche Gesundheitsratschläge gibt der Pekinger Arzt Richard Saint Cyr MD, www.myhealthbeijing.com Blog.
