Air Quality 50% open

Canada

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)
  • Available per air monitoring station/zone

How open is the data?

The original submission referred to a database presenting pollutant emissions of industries, available by regions. Whilst this information is of tremendous value, it does not match the Index's required data characteristics, which is air quality measurements (the difference is that emission data measure pollutants at the source, while air quality data measure their concentration in the air). Pollutant emission data meet almost all criteria of open data, but are not consistently updated (Comment submitter: "These are national data and are updated in an uneven way. Daily updated data are available from the provinces, territories and by cities who must report these data to the chief medical officer of health"). The review refers to another dataset from the National Air Pollution Surveillance Program (NAPS). It is available at: http://maps-cartes.ec.gc.ca/rnspa-naps/data.aspx. This data contains annual data per measurement stations for all required pollutants. It is therefore not updated. The downloaded file indicates that the data is incomplete. Therefore it is assumed that the download function is not bulk. The Environment and Climate Change Website, hosting the data, does not allow for commercial use (http://www.ec.gc.ca/default.asp?lang=En&xml=5830C36B-1773-4E3E-AF8C-B21F54633E0A#copy). Therefore the data is not considered openly licensed.

Thank you, Tracey P. Lauriault, for contributing to the Global Open Data Index.
