The fresh aroma after a summer downpour is one of life's pleasing scents. The earthy fragrance was named petrichor by Australian researchers in 1964. They described it as a combination of plant oils and the chemical compound geosmin which are released from the soil when it rains.
This past December, a team of scientists at MIT isolated the source of that fresh smell we sense after a satisfying rain. The scent called petrichor (petra, the Greek word for âstone,â and ichor, which means âthe blood of the gods,â) aerates when raindrops of a certain size and speed fall on porous earth, burst, and release chemical compounds from the ground into the air.
