Particulate air pollution contributes to the beauty of vibrant red sunsets. Unfortunately, it’s also a leading cause of death and disease. We are developing affordable air quality monitors that citizen scientists can deploy to monitor outdoor particulate matter concentrations in their own backyards. In this photograph, I have installed two of our monitors (the small black boxes on the tripod) next to the EPA particulate matter monitor for the City of Fort Collins (the large cream-colored box on the right). I am comparing continuous measurements taken by the filter sample and low-cost light-scattering sensor used in our monitor to hourly readings taken by the EPA monitor. The results look promising!
