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 seven objectives:

 

  • Objective 1: Identify and compare air quality sensor standards at different levels (regional national, and municipal) across Europe.
  • Objective 2: Investigate and compare the sensors used in existing citizen science initiatives (Including DIY sensors) measuring air quality.
  • Objective 3: Share best practices (incl. ideas and examples) for sensor guidelines in citizen science initiatives measuring air quality, and possibly other domains, to learn from.
  • Objective 4: (Optional) analyse the market of consumer grade air quality sensors.
  • Objective 5: By March 2022, create a user-friendly guideline for citizens and city officials that helps them select and calibrate sensors according to applicable data and interoperability standards for reference air quality sensors.
  • Objective 6: Pilot the developed guideline in at least one air quality citizen science initiative between April and December 2022.
  • Objective 7: Consolidate the guidelines with lessons learned from the pilot phase and further analysis by March 2023.
