Proposal  based on the discussions during the meeting (18/10/2018)

• Measurements with diffusion tubes in the surroundings of the schools (e.g. neighborhood profile)
• Co-location with official measurement station(s) (‘real world’ calibration)
• Use of shelter to protect the tubes
• Low cost sensors for measurements over time to monitor peak levels (of PM and/or NO₂)
• Co-location with stations measuring meteorological parameters (temperature, humidity, pressure…), particularly if sensors are used
• Counting of different vehicle types (easy to do)
• Use only one methodology for collecting the (measurement) data
• Links to media (newspapers, radio, TV, social media etc.)
