Question

Which scientists contributed to the determination of how CFCs in clouds in the upper atmosphere could destroy ozone molecules?
chemists only
meteorologists and chemists
astronomers and chemists
biologists, chemists, and physicians

Answer 1

meteorologists and chemists

Chemists worked out the CFC photochemistry (Molina & Rowland, Crutzen) and meteorologists/atmospheric scientists studied stratospheric clouds and circulation (e.g., Farman, Solomon) that enable the heterogeneous reactions that activate chlorine to destroy ozone.
