Petrichor is the scent that is created when the rain hits dry ground after a long period of dry weather. Bacteria, plants and even lightning can all play a role in the pleasant smell we experience after a thunderstorm. This scent has long been chased by scientists and even perfumers for its enduring appeal. First named by two Australian researchers in the 1960s as petrichor, it is the warm, earthy fragrance we experience when rain hits dry ground. It was already a signature fragrance being produced in Kannauj, a village in Uttar Pradesh, India in the 1960s and was called "mitti attar" (Earth's perfume). This village has been capturing the scent of rain and do it to this day.
For a bit more of a scientific look, you know how just before it rains, you can smell the rain? That's because the air becomes more humid and the ground begins to moisten. This process helps to speed up the activity of the actinobacteria and more geosmin is formed. When raindrops fall on the ground, especially porous surfaces such as loose soil or rough concrete, they will splatter and eject tiny particles called aerosols. The geosmin and other petrichor compounds that may be present on the ground or dissolved within the raindrop are released in aerosol form and carried by the wind to surrounding areas. If the rainfall is heavy enough, the petrichor scent can travel rapidly downwind and alert people that rain is soon on the way. The scent eventually goes away after the storm has passed and the ground begins to dry. This leaves the actinobacteria lying in wait – ready to help us know when it might rain again.
