    You know the smell dirt makes when its wet? It’s called petrichor and humans can smell it better than sharks smell blood in the water. It is detectable by the human nose at 0.4 parts per BILLION. This gave early humans a huge advantage in finding water when needed. https://en.m.wikipedia.org/wiki/Petrichor

      I was trying to think of that word just a few days ago when I went outside and could smell that a storm was coming, then my ADHD kicked in an I forgot about it.

      There is an Indian perfume base called Mitti Attar which tries to replicate this smell. It’s like damp moss at first scent, then develops into rain on hot sand. It is entrancing. Proper Mitti Attar sells for thousands and takes years to make.
