Publishing data on the World Air Quality Index project is free for every one. But it is also simple and straightforward: All you need to add data on the World Air Quality Index map is to provide a feed URL with the real-time information about the monitoring stations (name and location), the pollutants being measured and the real-time readings (together with the units, for instance milligrams or ppb).
Note that the data published on the World Air Quality Index map is only official data provided by each country respective Environmental Protection Agency (see the full EPA list). Those official data are monitored using professional BAM and TEOM-like Air Quality monitoring stations.
Those stations are not trivial, and do require constant maintenance and calibration by the the EPA professional field-engineering teams. Therefore, except from specific conditions (e.g. if there no coverage in a country or a given region / city), the World Air Quality Index project does not accept any form of data generated from non-professional Air Quality monitors.
The only exception to the above rule is the semi-professional GAIA air quality monitoring stations. But, even if more affordable than the BAM and TOEMs, the GAIA stations still require regular maintenance to ensure the high level of quality for the published data.
You can also check, for reference, the official feeds for Singapore, Peru or Netherlands and notice that they are all different.
The World Air Quality Index system will take care of regularly checking the data from the feed, and each time an update is available, it will be processed, converted to the US EPA scale AQI values, and publish on the World Air Quality Index website within minutes.
Also, although only PM2.5, PM10, Ozone, NO2, SO2 and CO Air Quality data is published, the system does collect more pollutants for forecasting purpose: Benzen, Toluen, Ethylbenzen, NOx, THC, NMHC, PM1, Formaldehyde, Mercury, Ammonia, Methan, Hydrogen sulfide, Nitrous acid, Phenol, Naphthalene, paraxylene (p-Xylen), metaxylene (m-Xylen), etc..
It is also possible to publish meteorological data: Temperature, Atmospheric Pressure, Humidity, Precipitation, Wind Speed, Wind Direction, Solar Radiation and UVI. If not provided, we will use other relevant meteorologic information sources.
