FlipFact of the Day: Changes in the weather can be detected by people with a keen sense of smell. The common odors that we catch a whiff of before, during, and after a storm are ozone (which smells somewhat like chlorine), petrichor (that sweet, grassy “rain-on-pavement” smell), and geosmin (the smell of damp earth, created by certain bacteria), respectively.
