When you smell rain, you are smelling this molecule: geosmin. It also contributes to the distinctive aromas of fish, beans, and beets...and it turns out to be useful for drawing mosquitoes into traps. https://www.acs.org/molecule-of-the-week/archive/g/geosmin.html #rain #chemistry

Strictly speaking that smell comes from the soil, not rain. Particularly wet soil.

Also not to be confused with the smell of ozone which accompanies thunderstorms.
