What data is expected?

Aggregate data about the emission of air pollutants especially those potentially harmful to human health (although it is not a requirement to include information on greenhouse gas emissions). Aggregate means national-level or available for at least three major cities. In order to satisfy the minimum requirements for this category, data must be available for the following pollutants and meet the following minimum criteria:

  • Particulate matter (PM) Levels
  • Sulphur oxides (SOx)
  • Nitrogen oxides (NOx)
  • Volatile organic compounds (VOCs)
  • Carbon monoxide (CO)
  • Updated on at least once a week.
  • Measured either at a national level by regions or at leasts in 3 big cities.

What data is available

  •   Openly licensed? Unsure (No URL given)
  •   Is the data available for free? Yes
  •   Is the data machine readable? No (n/a)
  •   Available in bulk? No
  •   Is the data provided on a timely and up to date basis? No

  •   Is data in digital form? Yes

Data is available for 2004-2013. The database offers quite useful filters (by type of pollution, pollutant, region etc.) Data are updated on a yearly basis.

The terms of use are not specified on publisher's website. I've asked the officials and have been told that data are freely available (and they could even offer an export on request). But he didn't specify the license.
