Guide to publishing Air Quality data on the World Air Quality Index project

Share: aqicn.org/publishingdata/ru/

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).


Qualification Criteria

Note that the data published on the World Air Quality Index project (see the map) is only official data provided by each country respective EPA (Environmental Protection Agency) (full EPA list). Those official data are monited using professional BAM and TEOM-like Air Quality monitoring stations. Therefore, except from very specific conditions (for instance when there is no coverage in a country), we do not accept any data generated from non-professional Air Quality monitors.

Feed format

Since almost each country has its own reporting format, we accept many kind of formats for the feeds: They can be in CSV, JSON or just plain text or HTML format. You can find at the bottom of this page 3 example for CSV, HTML and JSON.

You can also check, for reference, the official feeds for Singapore, Peru or Netherland and notice that they are all different.

Data ingestion

Our backend system takes 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 can 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 pubish meteorological data: Temperature, Atmospheric Pressure, Humidity, Precipitation, Wind Speed, Wind Direction, Solar Radiation and UVI. If not provided, we will use other relevant meterologic information sources.

If you have any question, just contact us.

..................
  • The "Station ID" is the unique identifer for each station, and it can just be a number (eg ID8373), or the concatenation of station city and station name (eg. "Beijing/Dongcheng").
  • By default, the station will be available via the url /city/country-name/city-name/station-name.
  • The "Station Name" must use latin characters, so the optional "Local Name" can be provided to localize the webpage.

  • The "Averaging" column is use to specify the duration of the value. The most common averaging is 1 hour. It is also the prefered one, as our backend system will automatically do the 8 hour averagin computation for the Ozone and Carbon Monoxyde.
  • In the case the readings are provided more freqently than every hour (for instance every 30 minutes or 10 minutes), you can either provide the raw readings for the given period, or just the hourly averaging: Our back-end system will anyway process data even between the hour.

О качестве воздуха и измерениях загрязнения:

О уровнях качества воздуха

- Индекс качества воздуха (ИКВ = AQI) ЗначенияУровни концерна здравоохранения
0 - 50 хорошо Качество воздуха считается удовлетворительным, и загрязнение воздуха представляется незначительным в пределах нормы.
51 -100 удовлетворительное Качество воздуха является приемлемым; однако некоторые загрязнители могут представлять опасность для людей, являющихся особо чувствительным к загрязнению воздуха.
101-150 Нездоровый для чувствительных групп Может оказывать эффект на особо чувствительную группу лиц. На среднего представителя не оказывает видимого воздействия.
151-200 нездоровый Каждый может начать испытывать последствия для своего здоровья; особо чувствительные люди могут испытывать более серьезные последствия.
201-300 Очень Нездоровый Опасность для здоровья от чрезвычайных условий. Это отразится, вероятно, на всем населении.
300+ опасный Опасность для здоровья: каждый человек может испытывать более серьезные последствия для здоровья
