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.

United Effort

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 a few of the institutions we have engaged:

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

United Data

The objective of the "Open Data Framework" is to provide unlimited and free access the world historical and real-time Air Quality data from the 100+ countries covered on aqicn.org and waqi.info

Everyone - both institutions as well as citizens - agrees that this is not only a good idea, but that it should just happen.

One for all and all for one

At the end of the day, developing the data-platform requires financial support.

Here is our proposal to the Clean Air Fund: Open Source Data Management System (OSDMS)

If you are interested in participating in this project proposal, either as a core member, either as a plugin contributor, or as a financial supporter, then please contact us via the contribute page

Free downloadable united database

Database Download

Thanks to all of our colleagues at the UN environment protection, the WHO, and the CCAC, the average daily air quality data from all air quality monitoring stations is now available for free download.

AQI calculation

All the values from the above database are already converted from the raw concentration (in mg/m3, ppm or ppb) to the "individual pollutant AQI", according to the US EPA standard (calculator). 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, ...)

Available Years

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 remote sensing data estimates, such as the one used by the WHO: who.int/airpollution/data/modelled-estimates/en/ You can for instance check the catalog from the ICARE project, which is archiving satellite data since 2000.

Contributing or Supporting this Project

The World Air Quality project might look like one of those big projects coming from organizations like the UN, ADB or WRI, but it is actually just a small team behind it.

Yet, despite our extensive outreach, our project has never received any financial support from such organizations, wether they are NGOs or governments.

The income comes from online advertising, as well as our GAIA air quality monitoring stations, but it is just enough to pay for the cloud infrastructure.

However, we are working on getting funding for the recruitment of a team dedicated to supporting and enhancing the air quality data platform.

If you would like to help, either by becoming one of our team member, either by providing financial support, or both, then contact us via this page: aqicn.org/contribute

Data Credits

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