About the Cover

Tropospheric ozone concentrations have trended downward in many U.S. cities since 2000. In Texas, however, concentrations and regulatory exceedances abruptly rose in Dallas-Fort Worth after 2020. This issue’s cover article explored this anomaly by analyzing more than 20 years of data on ozone concentrations and exceedances, nitrogen oxide concentrations, and meteorological variables. The results suggest that warmer atmospheric conditions associated with global warming are also increasing ground-level ozone concentrations in the study area.
