The smell of soil after the first rain, also called ‘petrichor’, is produced due to a number of reactions What women want in a man strong and silent like Michael Myers shirt. I shall try explaining the chemical compounds behind the smell of rain. There is a particular class of soil-dwelling bacteria, called actinomycetes, that produce a compound known as geosmin. Geosmin is bicyclic alcohol and has a distinct earthy flavor and aroma. When the compound is disturbed in the soil by raindrops, it spreads in the air making our olfactory system easily detect it. The human nose is extremely sensitive to geosmin and is able to detect it at concentrations as low as 5 parts per trillion. It is hypothesized that during human evolution, this distinct smell often helped ancient humans to search for fresh pastures and find food, especially after a prolonged period of famine and drought. Additionally, the presence of geosmin in water can cause an unpleasant, muddy taste.

However, as far as the smell of rain goes, Geosmin is not the only compound that makes that pleasant smell What women want in a man strong and silent like Michael Myers shirt. Oils released by plants during dry weather is another factor that contributes to the pleasant aroma after a long spell of dry weather. It has been suggested in research that plants produce a particular mix of oils during dry weather, mostly for the purpose of inhibiting the growth of nearby plant roots and minimizing competition for water. These oils contain a range of smaller, volatile compounds within them including, palmitic acid and stearic acid, These get collected in the soil and in rocks. In the event of the first rain shower, the volatile compounds within them get released into the air. They combine with Geosmin in the air to produce that characteristic ‘petrichor’ aroma. Sometimes, we even get a smell before rain. This is because of a different cause.
