The Two Ozone Problems in the Atmosphere - Tropospheric and Stratospheric

Explore the dual ozone challenges in the atmosphere through this 38-minute lecture from Yale University's "The Atmosphere, the Ocean and Environmental Change" course. Delve into the contrasting issues of excessive tropospheric ozone causing photochemical smog and dangerously low stratospheric ozone levels. Examine ozone properties, the formation of photochemical smog through UV radiation and nitrogen oxide reactions, and the health risks associated with high ozone concentrations. Learn about EPA-specified ozone limits, counties exceeding these thresholds, and the correlation between peak pollutant concentrations and daily rush hours. Gain insights into air pollutants, ozone creation processes, and primary pollutants through seven comprehensive chapters, offering a thorough understanding of these critical atmospheric phenomena.
