The unique scent that follows a rain shower is called petrichor. The term was coined by Australian scientists Isabel Joy Bear and Richard Grenfell Thomas in 1964 from the Greek words petra or petros (meaning stone or rock) and ichor (the fluid that flowed in the veins of the gods in Greek mythology). The scent is produced when rain falls on dry soil, and it's caused by an oil exuded by certain plants during dry periods, which is then absorbed by clay-based soils and rocks. During rain, the oil is released into the air along with another compound, geosmin, a metabolic by-product of certain actinobacteria, which produces the distinctive scent.

What You'll Learn
The science behind the fragrance
The fresh, earthy scent that fills the air after rainfall has a name: petrichor. The term was coined in 1964 by two Australian researchers, Isabel Joy Bear and R. G. Thomas, who published their findings in the journal Nature. The word comes from the Greek petra, meaning 'stone', and ichor, meaning the 'fluid that flows in the veins of the gods'.
Petrichor is the result of a combination of chemical compounds released from soil and plants during and after a rainfall event. One of the key compounds is geosmin, a metabolic byproduct of certain actinobacteria, which is emitted by wet soil. Geosmin has a strong, distinctive scent, which can be detected by the human nose even at low concentrations.
Another source of the smell is an oil exuded by certain plants during dry periods, which is then absorbed by clay-based soils and rocks. When it rains, the oil is released into the air, along with the bacteria and viruses from the soil, carried by aerosols. The scent is more noticeable after light rains because raindrops that move slower produce more aerosols.
The smell of rain has been a source of fascination and inspiration for poets and artists, and it holds a special place in many people's hearts. Some scientists speculate that humans may have developed an affinity for the smell of rain because, in ancient times, it signalled the end of a drought and the availability of fresh water.

Why humans enjoy the smell
The distinctive scent of fresh rain is not just the smell of wet dirt. It is a combination of the oil exuded by certain plants during dry periods, which is then absorbed by clay-based soils and rocks, and a compound called geosmin, a metabolic byproduct of certain actinobacteria, such as Streptomyces, which is emitted by wet soil. The scent is carried by aerosols, which are formed when the air from the pores of surfaces on which raindrops land creates small bubbles that float to the surface.
Humans have evolved the ability to detect geosmin, which is a volatile organic compound released by microorganisms in the ground, specifically cyanobacteria. This ability to detect geosmin may be linked to evolutionary advantage, as finding water sources was integral to human survival. Camels in the desert, for example, rely on their sense of smell to locate sources of water.
The scent of rain is also appealing to humans due to its primal and primitive attributes. The word "petrichor" is derived from the Greek words "petros", meaning stone, and "ichor", meaning fluid that flows from the veins of the gods. The scent of rain may evoke feelings of nostalgia and happiness, reminding people of the relief that the first rains of the season bring to dry landscapes, or the wonderful aroma of a hot beverage on a rainy day.
Additionally, the smell of rain can be calming and uplifting, with fragrances that are fresh, misty, and airy, with a touch of humidity. The scent of rain mixed with soil or the aroma of rainwater itself can evoke a sense of serenity and peace. The smell of rain can also be reminiscent of other pleasant scents, such as the fragrance of thousands of flowers, the scent of a verdant park after summer's first rain, or the aroma of new grass.

The role of bacteria and viruses
The smell of rain, or petrichor, is a phenomenon that has long been described in poetry and art. In 1916, James Joyce wrote in 'A Portrait of the Artist As a Young Man' about the "fragrant" trees and the "rain-sodden earth" that gave forth its "mortal odour".
Petrichor is caused by an oil exuded by certain plants during dry periods, which is then absorbed by clay-based soils and rocks. When it rains, the oil is released into the air along with another compound, geosmin, a metabolic by-product of certain actinobacteria, such as Streptomyces, which is emitted by wet soil, producing the distinctive scent.
Some scientists believe that humans appreciate the scent of rain for biological reasons, as our ancestors may have relied on rainy weather for survival. Camels in the desert rely on petrichor to locate sources of water, such as oases. The scent of rain can signal the end of a drought and the availability of fresh water, which may explain why humans often enjoy the smell.
