# Which Venus scientists discovered the hole in the ozone layer?

(Asked by: username_0 on 2021-10-13)

After `21:00` in *Venus: Earth’s Evil Twin or Just Misunderstood? (live public talk)* from the JPL YouTube channel the person being interviewed "[Sue Smrekar](https://science.jpl.nasa.gov/people/Smrekar/), Rocky Planet Geoscientist" (and Deputy Principal Investigator, Mars InSight lander) says that there is a link between the observation of Venus and the discovery of the hole in the ozone layer. Is there more information on this link? Which Venus researchers noticed the hole in the ozone layer? What comparisons were they trying to make when they noticed this?

I wasn't sure if I should post this question here because of the observation of Venus or if I should post it in Earth Science SE.

I call BS. Being [slightly familiar with the discovery of the ozone hole](https://space.stackexchange.com/a/49535/2752), I have read about the people who did discover the ozone hole. They were British geophysicists. I cannot find a single article by JC Farman, BG Gardiner, or JD Shanklin on the atmosphere of Venus.
