What is the name of your initiative?
Measure Together (Samen Meten)
How would you describe the main mission of your initiative?
  • Measure/monitor air quality
  • Raise awareness/education

 

Please provide a short description of your initiative* (What is being done? Who is participating? What are your main goals?) This text will appear on the main page.
Samen Meten is an infrastructure for data and knowledge sharing for citizen scientists interested in air quality. We provide a platform where citizens can find their own data and the data of others. In addition, the data can be analysed via the ‘Analyse together tool’. New citizen scientists can also find information on how and where to start measuring air quality. Currently also data on noise and water quality is added.
Who is your main audience?
  • Citizens

Would you like to share with us any additional information? (Max 300 words)
There is high demand for measuring air quality among citizens, in the Netherlands in both urban AND rural areas.
With low-cost sensors, quality is not very high, however the strength is the quantity, to have a network of many sensors that together provide an interesting view on the air quality in one place.
As RIVM we also provide calibration of the low-cost sensors with the official measuring stations. We are also working on integrating the citizen science sensors in the official national maps, still this remains a challenge due to the heterogeneity of the used sensors.

Measurements and perceptions of air quality

Measurements and perceptions of air quality

Location: Paris, France

Description: The aim of the project is to improve knowledge of the levels of pollution at the heart of traffic, while testing a new network of measurements, and to understand the perception of Ile-de-France residents with regard to air quality. These innovations will make it possible to raise awareness of air quality in Ile-de-France, and ultimately to identify the levers of commitment of Ile-de-France residents to reduce air pollution.

H2020 SOCIO-BEE

Location: Bilbao, Spain

Description: The H2020 SOCIO-BEE project aims to encourage citizens to take an active role in the fight against climate change through citizen science using disruptive technologies such as drones and wearables articulated by a framework called AcadeMe. More specifically, Socio-Bee aims to involve different segments of citizens (young people under 16 years of age, older adults over 65 years, and people who commute by car or through public transport in large cities or suburbs) in different scientific endeavors..
