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.

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 Note that all the figures are converted to AQI using the US EPA standard: i.e. we do not publish the raw concentrations, but only the AQI.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 PM_2.5, they correspond to the PM_2.5 individual AQI (noted as AQI_PM2.5). If you want to calculate the overall AQI, aka composite AQI, you need to take the maximum of all individual AQI:

AQI = max( AQI_PM2.5, AQI_PM10, AQI_O3, ...)
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.

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