History of community-led air monitoring effortsNew opportunities with next generation sensorsDemocratizing data and scienceLeveraging community knowledge and capacityCommunity air monitoring network as a complement to regulatory monitoringCommunity monitoring and low-cost sensorsSlide3
background Slide4Slide5
Locations of regulatory monitors in Imperial County
PM10 standards unmet
High
rates of asthma
Few regulatory monitors
Need
for
more local air
quality data
Air quality is a community prioritySlide6

116 episodes were identified by government monitors1,426 episodes were identified by community monitors An episode defined as hourly concentrations above 35 ug/m

Community responseSlide22
Lessons LearnedEarly community engagement is criticalProvides local knowledge, relationships, capacitiesBuilds trustImproves utility of dataFunding is criticalTraining should be integrated to build capacity and sustainabilityNature of contaminantMonitoring science and sitingHardware/software troubleshootingMonitor calibrationQA/QCData transfer/flowCommunity should guide decision-making Monitor locationsData dissemination and visualization methods/platforms
Information/messaging that is understandable and usefulSlide23
Use of low-cost sensors in a community air monitoring network provides useful, actionable informationTechnical challenges still occur despite ease of use and regardless of operatorCommunity engagement benefits all partnersPlan with sustainability and community ownership as a stated goalConclusionsSlide24
