We are working on designing and building our own PM2.5 and trace gas pollutant air monitors in the Westervelt Air Sensors lab. We are also working on deploying these and off-the-shelf sensors in overburdened communities where air monitoring is scarce. We are partnering with NYC area high schools to both demonstrate the science and engineering behind air sensors and engaging students in research projects as they deploy their sensors around NYC.
We have also established a sensor intercomparison site at the Air Sensors Lab rooftop monitoring location at LDEO. Here we have ~10 consumer-grade sensors plus some custom-built sensors in comparison with a GRIMM reference monitor. We will use this data to evaluate the performance of various air sensors and develop correction factors using statistical models.
