Why Can You Smell Rain?

When those first fat drops of summer rain fall to the hot, dry ground, have you ever noticed a distinctive odor? I have childhood memories of family members who were farmers describing how they could always “smell rain†right before a storm.
Of course rain itself has no scent. But moments before a rain event, an “earthy†smell known as petrichor does permeate the air. People call it musky, fresh – generally pleasant.
