Short summary
We present a new miniature instrument to measure nitrogen dioxide (NO2) using cavity-enhanced spectroscopy. NO2 contributes to the formation of pollutants such as ozone and particulate matter, and its concentration can vary widely near sources. We developed this lightweight (3.05 kg) low-power (<35 W) instrument to measure NO2 on uncrewed aircraft vehicles (UAVs) and demonstrate that it has the accuracy and precision needed for atmospheric field measurements.
