Air quality can vary substantially between neighborhoods in the same city, and nitrogen dioxide (NO2) pollution has been shown to disproportionately harm communities of color and low-income communities in the U.S. Urban ozone (O3) is produced as a nonlinear function of NO2, suggesting O3 is sensitive to both the abundance and distribution of NO2 within cities. This work explores chemical relationships between NO2 inequalities and city-wide O3, describing nonlinear variability in surface O3 with space-based NO2 observations from TROPOMI at the census tract scale. As part of this work, we identify opportunities for regulatory co-benefits in polluted U.S. urban areas.
