Обзор
UV-C radiation (< 240 nm) and UV-B (240–320 nm) break ozone back into molecular oxygen and atomic oxygen. This absorption of UV is precisely what protects life on Earth. The steady-state balance between ozone formation and decomposition maintains the ozone layer thickness.

Пример из жизни
Sunscreen with high SPF is needed because not all UV is filtered by ozone — the remaining UV-A and some UV-B still reach the surface.
Промышленное значение
Understanding ozone photochemistry is critical for monitoring the ozone hole and predicting UV exposure levels worldwide.
