"I was perhaps only about 3 or 4 years old when I recall having my first experience of ‚Äúpetrichor‚Äù the scent of rain on dry earth. On that particular day, I remember running around the back of our house which was a huge open space with a forest and a narrow path amongst¬†the grass and bushes that led to a small ravine. The previous¬†days had been extremely hot and I felt elated when the rains poured down. I enjoyed splashing in the rain but I remember as I walked further away from our house into the forest, the distinctive smell which seems to be coming from the earth and which still remains¬†very pronounced in my memory. I was too young at the time to make any associations but noticed as I grew older, that my nose usually picked up that scent after a burst of rain, if I am outside. I learnt later of the world ‚ÄúPertichor‚Äù which is constructed¬†from Greek, petros, meaning ‚Äústone‚Äù + ichor, the fluid that flows in the veins of gods in Greek mythology. I have also learnt since that the term was developed¬†by two Australian researchers, Bear and Thomas, who described that the smell is derived¬†from an oil exuded by certain plants during the dry period and during the rain, the oil is released into the air along with another compound, geosmin.
