With the COVID-19 spreading out all over the world, the World Air Quality Index project team saw a surge in requests for global data covering the whole world map. As a result, the WAQI project is now providing a new dedicated data-set, updated 3 times a day, and covering about 380 major cities in the world, from January 2015 until now.
The data for each major cities is based on the average (median) of several stations. The data set provides min, max, median and standard deviation for each of the 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 per day using all AQI values for available stations

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:

About the Air Quality and Pollution Measurement:
About the Air Quality Levels
AQI
Air Pollution Level
Health Implications
Cautionary Statement (for PM2.5)
0 - 50
Good
Air quality is considered satisfactory, and air pollution poses little or no risk
None
51 -100
Moderate
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
101-150
Unhealthy for Sensitive Groups
Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
151-200
Unhealthy
Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects
Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion
201-300
Very Unhealthy
Health warnings of emergency conditions. The entire population is more likely to be affected.
Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.
300+
Hazardous
Health alert: everyone may experience more serious health effects
