You asked us a question. Why does rain have such a distinctive smell?
A rainstorm has all kinds of different odors. Three are common the world round.
You know that sweet fresh smell that rolls in on the wind right before a storm? That's ozone you smell. Ozone is a form of oxygen. It is created by lightning. It floats down from much higher altitudes.
Ozone protects our planet from the sun's harmful rays. That happens way up in the atmosphere. Down at ground level, harmful concentrations of the gas create things like smog.
But let's get back to the question.
Another smell wafts up after the rain starts to fall. That smell is petrichor. The smell occurs when plant oils get displaced by rain and are carried into the air.
Last but not least is the damp, musky smell that happens after a storm passes. That smell is geosmin. It is an organic compound. It's created by bacteria in soil.
There have been many attempts to bottle the perfectly heady smell of rain. But so far, no one's been able to do so.
Look out for when the next good summer storm rolls in. Take the time to drink in those sweet, elusive scents.
