英文摘要 | Air pollution disproportionately burdens communities of color and lower-income communities in U.S. cities. We have generally lacked city-wide concentration measurements that resolve the steep spatiotemporal gradients of primary pollutants required to describe intra-urban air pollution inequality. Here, we use observations from the recently-launched TROPospheric Ozone Monitoring Instrument (TROPOMI) satellite sensor and physics-based oversampling to describe nitrogen dioxide (NO2) disparities with race, ethnicity, and income in 52 U.S. cities (June 2018–February 2020). We report average U.S.-urban census tract-level NO2 inequalities of 28 ± 2% (race-ethnicity and income combined), with many populous cities experiencing even greater inequalities. Using observations and inventories, we find diesel traffic is the dominant source of NO2 disparities, and that a 62% reduction in diesel emissions would decrease race-ethnicity and income inequalities by 37%. We add evidence that TROPOMI resolves tract-scale NO2 differences using relationships with urban segregation patterns and spatial variability in column-to-surface correlations. |
