Petrichor in Talk Story

Aloha...

I have often wondered what that wonderful fragrance is called that we smell after the first rain... well now I have an answer:

Petrichor is the pleasant smell that often accompanies the first rain after a long period of warm, dry weather in certain regions... It was named by two Australian researchers, who discovered that the smell is an oily essence emitted from rocks or soils...The oil is a complicated mixture of at least fifty different compounds, rather like a perfume...

So now we know...! (smiles)
