The Secret of Petrichor When the first drops of rain fall onto dry earth after a long period of warm weather a distinct and pleasant earthy scent fills the air. This fragrance is known as petrichor. The smell actually comes from a combination of plant oils and a chemical compound called geosmin which is produced by soil dwelling bacteria. When rain hits the ground it traps tiny air bubbles against the soil which then pop and release these scents into the air as an aerosol. Humans are incredibly sensitive to this smell and can detect it even at very low concentrations. It is a natural signal that the dry spell has ended and the earth is being renewed by water.
