What is the smell of rain called?

What is the smell when it rains?

The smell of rain, called petrichor, is a mix of earthy, pleasant scents from plant oils, soil bacteria (releasing geosmin), and sometimes a sharp, "electric" scent of ozone from lightning before a storm. When rain hits dry ground, it aerosolizes these compounds, releasing them into the air, creating that fresh, distinctive aroma we often smell as a storm approaches or begins.
 

Why can humans smell petrichor?

Humans are so sensitive to petrichor, the earthy smell after rain, primarily due to evolution, as it signaled vital water sources and fertile land, and our noses detect its key compound, geosmin, at incredibly low, parts-per-trillion levels, a sensitivity far exceeding that of sharks detecting blood. This powerful scent, released by soil bacteria (Actinomycetes) when raindrops hit the ground, evokes strong emotional and memory responses linked to survival, making it a deeply ingrained and pleasant experience.
