The Comparability working group aims to develop a basic set of guidelines that informs citizens and city officials on which air quality sensors to use to ensure the comparability of data with other citizen science initiatives, as well as with official observations. This working group has six objectives:


  • Objective 1: Co-design a structure for the inventory of air quality monitoring activities and approaches.
  • Objective 2: Validate the co-designed structure by receiving feedback from the WG members and testing it to gather information about at least five different cities and organizations.
  • Objective 3: Continuously add to the inventory by completing it for cities and organizations within and outside the WG.
  • Objective 4: Create an online interactive tool(s) for city officials and citizen science initiatives that facilitate information sharing across cities and organizations by clarifying who is involved in air quality monitoring activities and how.
  • Objective 5: Pilot the developed tool(s) by adding information about at least 50 air quality monitoring initiatives between April and December 2022.
  • Objective 6: Consolidate the tool with lessons learned from the pilot phase and further analysis by March 2023.
