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)

Reviewer comments

Changed machine readability and bulk to unsure. We can't find the proper link to the raw data, only the maps. Even when searched in Google you can only find some test projects. License is not open according to the Open Definition (Non-commercial and Non-derivative obstruct the freedom of using it for all purposes). They are surely working on Open Data on a technical level, but the data is not available / accessible for the general public.
