Nitrogen dioxide (NO2) is a prevalent pollutant, especially in urban areas. It negatively affects human health and the environment, plus it reacts chemically in the atmosphere to form other harmful pollutants including ozone. We use a network of four remote sensing instruments that measure NO2, called Pandora spectrometers, in the Boston area to study urban pollution. Each Pandora is on a custom, automatic measurement schedule that enables us to monitor and map the amount of NO2 in multiple directions around a single instrument. Early data looks promising: it aligns with expectations, including higher levels of pollution in downtown compared to the suburbs, and confirms that it is feasible to map pollution in the vicinity using a single Pandora. Additionally, we apply the NO2 data to understand changes in pollution over the course of the day and under various wind conditions. Finally, we leverage our data to help validate NO2 observations from the recently-launched TEMPO satellite in the Boston area. The success of our early measurements using the custom measurement schedule supports more widespread adoption of this methodology for observing urban pollution.
