The fresh aroma after a summer downpour is one of life's pleasing scents. The earthy fragrance was named petrichor by Australian researchers in 1964. They described it as a combination of plant oils and the chemical compound geosmin which are released from the soil when it rains.
As it turns out, the smells people associate with rainstorms can be caused by a number of things. One of the more pleasant rain smells, the one we often notice in the woods, is actually caused by bacteria! Actinomycetes, a type of filamentous bacteria, grow in soil when conditions are damp and warm.
