Since the beginning, the World Air Quality Index (WAQI) project team has always been keen on providing a transparent Air Quality Information to the world citizens.

The WAQI project has also always been keen on providing historical Air Quality Data to relevant institutions and organizations working in the area of environmental awareness, air quality monitoring, as well as health and epidemiological studies. Here are few of our partners and colleagues to which we have been providing historical air quality data information:


United Framework



In order to make the historical Air Quality Data dissemination even more relevant, the World Air Quality Index team has been investigating with the most relevant international institutions the possibility to setup an open data framework. Here are fews of the institutions we have engaged:

  • WHO - World Health Organization
  • UNEP - United Nation Environmental Program
  • UNIDO - United Nation Industrial Development Organization
  • WMO - World Meteorological Organization
  • GEO - Group on Earth Observations
  • WRI - World Resource Institute
  • CCA - Climate & Clean Air Coalition
  • UNFCCC - United Nations Framework Convention on Climate Change

The open data framework objective is to provide unlimited and free access the world historical and real-time Air Quality data from the 100+ countries covered on aqicn.org Everyone - both institutions as well as citizens - agrees that this is not only a good idea, but that it should *just* happen.

Free Downloadable Database

Database Download
The daily average air quality data for all of the stations can be downloaded freely from the form below. Note that all the figures are converted to AQI using the US EPA standard: i.e. we do not publish the raw concentrations, but only the AQI.

notes:

In the above data, we publish the "Individual pollutant" Air Quality index. For instance, if you check the figures for PM2.5, they correspond to the PM2.5 individual AQI (noted as AQIPM2.5). If you want to calculate the overall AQI, aka composite AQI, you need to take the maximum of all individual AQI:

AQI = max( AQIPM2.5, AQIPM10, AQIO3, ...)

The Air Quality data is currently only available since ~2012. If you need data before this period, we recommend to either contact the originating EPA, or consider using estimates based on remote sensing data. You can for instance check the catalog from the AERIS/ICARE project, which is archiving satellite data since 2000.

Inquiry & Registration

If the above data does not work for you, and you are from an international institution, organization or university you can register your interest with the form below. Note that this registration is only at intent level, for us to consolidate the list of all interested parties, and does not bound you, nor the world air quality index project, to any obligations.

✋ Unfortunately, due to the lack of resource we are unable to process manual requests.
We did try to ask support from the UN, WHO, WMO and other relevant organizations, such as WRI or EDF, but without any success 🌸.
If you want to help, contact them and tell them to support the aqicn.org Open Data Platform project 💨.
Or if you are part of an organization who could help the aqicn.org project contact us 🙏.

Write few words about your request - eg: "I would like to get the daily max AQI for Berlin for Winter 2014", "I would like to know the hourly concentration of SO2 for Civil Lines in Delhi on June 18th 2015", "I would like to support your project and give you hand", ..

Contributing or Supporting this Project

✋The World Air Quality project might look like one of those big projects coming from big organizations... but it is actually just a small, but lean, team behind it.

Despite its expensive outreach, the project has never received any financial support from any of NGO nor from any government🌸

The project income comes online advertising, but it is just enough to pay the cloud infrastructure. So, yes, all contributors are having a real job at the same time🙏

Yet, rather than asking for financial support, we prefer asking for contributors who can help with their time. Check the contribute page for more info.

❤️❤️❤️

If you do not have time to contribute, but still would like to help and support our project, what about getting one of our cool GAIA air quality monitoring station? ☀️💨👌

Data Credits

The open data framework would not be possible without the work from the worldwide EPA, which should get the credits for their monitoring programs.

O pomiarach jakości powietrza i zanieczyszczeń:

O Poziomach Jakości Powietrza

- Wartości Indeksu Jakości Powietrza (AQI)Poziomy zagrożenia zdrowia
0 - 50 Dobra 0-50: Dobra - Jakość powietrza jest uznawana za zadowalającą, a zanieczyszczenie powietrza stanowi niewielkie ryzyko lub jego brak.
51 -100 Średnia 50-100: Średnia - Jakość powietrza jest dopuszczalna; jednak niektóre zanieczyszczenia mogą być umiarkowanie szkodliwe dla bardzo małej liczby osób, które są niezwykle wrażliwe na zanieczyszczenie powietrza.
101-150 Niezdrowa dla osób wrażliwych 100-150: Niezdrowe dla wrażliwych osób - u osób wrażliwych mogą wystąpić negatywne skutki dla zdrowia. Większość populacji może nie odczuwać negatywnych objawów.
151-200 Niezdrowa 150-200: Niezdrowe - Każdy może zacząć doświadczać negatywnych skutków zdrowotnych; U osób wrażliwych mogą wystąpić poważniejsze skutki zdrowotne.
201-300 Bardzo niezdrowa 200-300: Bardzo niezdrowe - Ostrzeżenie zdrowotne, poziom alarmowy. Bardzo prawdopodobny negatywny wpływ na całą populację.
300+ Zagrożenie dla życia 300 : Niebezpieczny - Alarm Zdrowotny: każdy może doświadczyć poważniejszych skutków zdrowotnych.
