RIVM is responsible for monitoring air quality in the Netherlands. With the Samen Meten (Measure Together) initiative, RIVM supports citizens who want to measure air quality themselves. The (Dutch) website offers an overview of the materials, sensors and devices that are available for air quality measurements. We also provide information about citizen science projects and the sharing and use of data through the data portal. The data portal shows also the Luftdaten measurements in the Netherlands, and NO2 Palmes tube data by citizens. The (Dutch) activities for the European Clean Air day will be promoted on the website and through the Samen Meten newsletter, or contact samenmeten@rivm.nl

DIY Science Lab promotes awareness and mobilizes multi-stakeholder engagement in Hungary.


Sensor.Community is a Citizen Science project that started in Stuttgart, Germany. The initial goal was to simply quantify air quality data and better equip local citizens in their understanding of how particulate matter truly affects our everyday lives in response to the increasing ecological concerns. Sensor.Community gathered organic interest and build with the combined expertise of its members a do-it-yourself kit that is quickly assembled and can be added to homes, schools, companies, and more.
