What's the word for the smell of rain?

• Petrichor:The Oxford English Dictionary defines petrichor as: “A pleasant, distinctive smell frequently accompanying the first rain after a long period of warm, dry weather in certain regions.” The word was coined by scientists in Australia in 1964 to describe the unique, earthy smell associated with rain. The fragrance we experience when rain hits the ground is produced by bacteria, along with certain chemical compounds like ozone, geosmin, and plant oils. The scent has long been chased by scientists and even perfumers for its enduring appeal.
