Air Quality 85% open


What data is expected?

Data about the daily mean concentration of air pollutants, especially those potentially harmful to human health. Data should be available for all air monitoring stations or air monitoring zones in a country. The Index focusses on key pollutants as defined by the World Health Organisation. See our methodology section for more information.

  • Particulate matter (PM)
  • Sulphur oxides (SOx)
  • Nitrogen oxides (NOx)
  • Carbon monoxide (CO)
  • Ozone
  • Volatile organic compounds (VOCs)
