Not a bad office for the day

Particulate air pollution contributes to the beauty of vibrant red sunsets. Unfortunately, it’s also a leading risk factor for death and disease. We are developing affordable air quality monitors that citizen scientists can deploy to monitor particulate matter concentrations in their own backyards. In this photograph, I am comparing measurements taken by two of our monitors (the small black boxes on the tripod) to measurements taken by the EPA-approved monitor for the City of Fort Collins (the large cream-colored box on the right). The results look promising! By making monitors more affordable—while maintaining accuracy—we can measure particulate matter concentrations in a greater number of locations and learn how air pollution varies across a city like Fort Collins.
