Spring bike ride in #Montreal ‘s East End. Going back I pass the mobile trailer that houses an #airquality station. Back in 2019 I was running a hyper-local air quality project using #lowcost sensors for #PM25 deployed on residents’ balconies. The data contributed to driving discussions between the Department of Defense (that hosts the station) and the City to assess the impact of traffic and the port’s activities. For years after the trailer sat unused in the parking lot, but now it is working as station 25: https://donnees.montreal.ca/dataset/projet-station-longue-pointe-25
