Well I'll be. TIL geosmin is one of the molecules contributing to what we call petrichor. I didn't see mention of the phenomenon in the ozone article and I can't say I could reliably identify the scent, though I'll keep this in mind during the next thunderstorm.

The smell of rain has a name, though not explicitly for the rain itself, but the musty soil and permeating moss and undergrowth. It's called petrichor. And yes it is one of my favorites.
