June 21 - The Smell of Rain

On a hot day, the smell of wet pavement announces a rain shower just before the first few drops dot the sidewalk with dark splotches. It smells like rainbows. The smell fades quickly when the rain begins in earnest and streets are soaked.

I've read that the smell is not wet pavement at all, but rather ozone or some other phenomenon in the sky, but I don't believe it. I never smell it in the woods, at the beach or in the middle of a lake.
