Ground-level ozone is a toxic air pollutant regulated by the Environmental Protection Agency that is produced from reactions of nitrogen oxides (NOx = NO + NO2) and volatile organic compounds in the presence of sunlight. In cities, NOx is primarily emitted from fossil fuel combustion and VOCs are emitted from oil and gas operations, the use of personal care products, and natural sources including trees and plants. Implementing successful regulations aimed at reducing ozone concentrations is difficult because the production of ozone is complex and nonlinear with respect to its precursors. Understanding ozone chemistry in a city requires the careful analysis of NOx and VOC concentrations, which relies on many VOC measurements that are not routinely monitored. However, satellite remote sensing can be used to observe trace gases relevant to ozone formation globally, which can help fill in data gaps in regions with little or no other observations. In this study, we investigate the relationship between high-resolution satellite observations and ground-level air quality. We find that there is a relationship between satellite observations and ground-level ozone and other secondary pollutant production. Ultimately, we aim to provide a method others can follow to help interpret ground-level air quality using satellite observations.
