The fresh smell that appears after rain is known as "petrichor." It is caused by a combination of factors. When rain falls, it can disturb and release volatile compounds from the soil, plants, and bacteria. These compounds are then carried through the air and mix with ozone to produce the characteristic smell. Additionally, the rain can also help to clean the air of pollutants, contributing to the refreshing scent experienced after a rainfall.
