Bacteria, plants and even lightning can all play a role in the pleasant smell we experience after a thunderstorm; that of clean air and wet earth. Known as petrichor, the scent has long been chased by scientists and even perfumers for its enduring appeal.
Why does the smell of rain smell good?
Petrichor — the term was coined in 1964 by two Australian scientists studying the smells of wet weather — is derived from a pair of chemical reactions. These aromatic compounds combine to create the pleasant petrichor scent when rain hits the ground. Another scent associated with rain is ozone.
Do you love the smell of rain?
And it’s no wonder: That distinct, earthy odor wafting through the air after a rainstorm is a delightful scent that everyone loves. Turns out, there’s a reason for that: When the rain hits the ground, it triggers the release of chemicals, which combine with other chemicals to create the aroma.

But moments before a rain event, an “earthy” smell known as petrichor does permeate the air. People call it musky, fresh — generally pleasant. This smell actually comes from the moistening of the ground. A byproduct of their activity is an organic compound called geosmin, which contributes to the petrichor scent.
What is the smell of sperm?
Semen normally smells like ammonia, bleach, or chlorine. Semen is about 1 percent sperm and 99 percent other compounds, enzymes, proteins, and minerals. Many of these substances are alkaline.
Do people like smell of rain?
The human nose is extremely sensitive to geosmin and is able to detect it at concentrations as low as 400 parts per trillion. Some scientists believe that humans appreciate the rain scent because ancestors may have relied on rainy weather for survival.
How do you describe the smell of rain?

What is the human nose most sensitive to?
24, 1667–1678 (2018). Petrichor, the distinct way that dry earth smells after it rains, comes in part from bacteria in the soil that release a chemical odorant called geosmin. The human nose is quite sensitive to the odor, as is that of the fruit fly, Drosophila melanogaster.
Can you smell rain before it rains?
There are times we can smell a rain shower or a thunderstorm coming well in advance of the actual rain. If you’re one of those people, congratulations, you have a sensitive nose! That sensitive nose is picking up on three things: ozone, petrichor, and geosmin.

What causes the smell after the first rain?
After rain, some amount of ozone gas present in the atmosphere dissolves with the rainwater due to which the smell or aroma arises. The second reason is the existence of bacteria.
Why does rain smell so good?
It breaks apart soil and releases minerals trapped inside, and it reacts with chemicals, such as gasoline, giving them a stronger smell. These reactions generally produce more unpleasant smells than bacteria spores, which is why the after-the-rain smell isn’t always a good one.
What does fresh rain smell like?
Another after-the-rain smell comes from volatile oils that plants and trees release. The oil then collects on surfaces such as rocks. The rain reacts with the oil on the rocks and carries it as a gas through the air. This scent is like the bacteria spores in that most people consider it a pleasant, fresh smell.
What is the smell before it rains?
The odor you smell before the rain comes from ozone, a form of oxygen which is produced by lightning, and ionized gases in the atmosphere. The name given to the characteristic odor of rain after it rains, especially following a dry spell, is petrichor.
