Back in the days when COVID-19 was spreading worldwide, the World Air Quality Index project team saw a surge in requests for global data covering the entire world map. As a result, the WAQI project has been providing an open, free, dedicated dataset, updated 3 times a day and covering the air quality statistics for over 380 major cities worldwide, from January 2015 to the present.
The data for each major city is based on the average (median) of several stations. The provides min, max, median, and standard deviation for each air pollutant species (PM2.5, PM10, Ozone,...) as well as meteorological data (Wind, Temperature, ...).
All air pollutant species are converted to the US EPA standard (i.e. no raw concentrations). All dates are UTC-based.
The count column is the number of samples used for calculating the median and standard deviation.
The city-median value is computed daily using all available AQI values from stations.

Keeping the air we breathe transparent shouldn't come with a price tag. Help us keep this service free!
Obviously, you should be asking why the data for the second halves of 2015-2019 is not available. The answer is simple: to reduce the monthly cost of infrastructure, we need to purge older data from the database. With proper funding, we can reactivate a database with larger storage and export all missing data, including data from before 2015.
If you want to help, you can make a small donation via this link. You can also drop a small message to the Clean Air Fund to let them know we need their support.

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 send us a message with the form below:
