Reply to comment by slogginmagoggin in I recently learned that humans can smell rain / petrichor (ozone and geosmin) better than sharks smell blood, now considering we don't have any extra hyper specific olfactory organs like some other animals do, how do we achieve this level of detection? by Corvuscoraxaphro

We can see signs of water much easier and longer than we can smell them. Just look at the ground, maybe scratch away the dry dirt on top.
