The smell of rain, known scientifically as petrichor, is an earthy, fresh aroma produced when moisture hits dry soil, releasing compounds like geosmin from bacteria and oils from plants. Coined in 1964, the term describes the scent resulting from the combination of these soil compounds, atmospheric ozone, and plant oils, often intensifying after dry spells.

Humans are Extraordinarily Sensitive to the Smell of Rain, known as Petrichor, primarily due to the compound geosmin. We can detect Geosmin at parts-per-trillion levels, whereas sharks typically detect blood in water at parts-per-million or parts-per-billion concentrations. This means humans are roughly 200,000 times more sensitive to the scent of rain than sharks are to blood.

Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth.

Raindrops rarely exceed 6 mm (0.2 inch) in diameter because they become unstable when larger than this and break up during their fall. The terminal velocities of raindrops at ground level range from 2 metres per second (7 feet per second) for the smallest to…ground and where is the wettest place in the world?
