What is the name of this fragrance?

The scent that is released after a rain shower is known as petrichor. The word "petrichor" is derived from the Greek, where "petra" means rock and "ichor" refers to the divine fluid that flows through the veins of the gods. It is a fitting name, as petrichor seems to contain the essence of the earth itself.

Where does it come from?

Petrichor is formed by a combination of several factors. A major contribution comes from certain chemicals secreted by soil bacteria called actinomycetes. These bacteria live in the soil and produce odorants, such as geosmin, which give petrichor its characteristic earthy odor. In addition, plant oils and volatiles that accumulate on surfaces such as rocks and soil also contribute to the odor.

How long must it have been dry to smell this?

In order for the petrichor scent to be detected, there must be sufficient moisture in the soil before it rains. If it has been dry for a long time, the soil and other surfaces can absorb the odorous compounds. When it then rains, these stored scents are released and mix with the fresh raindrops, creating petrichor. It is generally assumed that it must be dry for at least several weeks before petrichor is clearly detectable.

Conclusion

Petrichor , the scent released during rain, is an intriguing phenomenon that captivates our senses and connects us to the earth. The scent is created by the chemicals released by soil bacteria and the accumulation of volatiles on surfaces. It requires a period of dryness for the scent to develop and be released during a rain shower.
