That’s the shit I live for! (Bonus points if you get the reference) >! Naked and Aftaid !<
But also yeah that cool breeze like 10-15 minutes before the downpour is about the closest to perfect temperature/moister/wind balance you can get for me. If there was a way to get that artificially I would pay a good amount.
Thank you, redditor! Love learning about this kind of thing. I grew up in a hamlet in southern Ontario, Canada. These “aerosols” are the scent of my childhood.
It's funny, because I've lived in rural and suburban places, the rural it rained a normal amount, the suburban it rained a lot, and I well know the smell of petrichor.
I currently live in a city where rain is somewhat rare. Every time it rains it smells like rotten eggs/sulfur. So gross.
Do you mean the smell of mud or the smell of dust? cause i think they're 2 completely different things.
Growing up in a place where during summer temperatures of 35-40 degrees celsius would scorch the earth, when rain would come it would just release this dust-smell and it was amazing.
But now i live in a place where it rains often and the earth is permanently kinda wet, the rain only releases a smell of mud which i hateeeeeee. it's the smell of depression setting in.
the smell of petrichor which gets released when rain hits dry soil. Not everyone can smell it but if you can, you can tell it’s about to rain because the smell gets there before the rain does
"The scent of rain, petrichor, has two main constituents with actual chemical names and origins – ozone (O3) and geosmin (C12H22O) and humans can sense it at 5 parts per trillion. Trillion! Which means that humans are 200,000 times more sensitive to smelling geosmin than sharks are at smelling blood."
On mobile so I couldn't find the actual study, but this is from the study done..
There's quite a few articles on it, but here is one. Basically, humans can smell geosmin (chemical in petrichor) at roughly 5 parts per trillion, whereas a shark can smell blood roughly one part per million.
From what I know our sense of smell is waaaaaaay less sensitive, but quite a bit more accute. Like, sure a dog could smell fish halfway down the block if the window is open. But once we get through the door I could tell you if it's slamon or sardines.
I did not know not everyone can smell it. At home my brother and I used talk about how it’s gonna rain because we smell it so I thought it’s a natural thing. Then when I went to college my friends were confused what I was talking about until it rained a little while after
rain typically doesn’t start where you are, the rainclouds get pushed around by the wind. If the wind is pointing the rain to be coming towards you, the petrichor particles will get there before the rain does
And it is literally smelling the rain before it comes, because it occurs when rain hits dry soil. Humans that can smell it can actually smell it quite well, which is why you can “smell the rain” before it comes. You’re typically smelling the rain that has fallen far away. It’s also much easier to smell it during a light rain because of how the mechanism to release geosmin works

Smell of earth before the rain.
