Petrichor: History & Art

Petrichor (/ˈpɛtʃrɪkɔːr/) is the earthy scent often associated with rain falling on dry soil or rock. The term was introduced by Australian researchers Isabel Joy Bear and Richard Grenfell Thomas in a 1964 paper in Nature. Bear and Thomas used the term for an odour released from rock or soil materials after dry conditions when they are exposed to moisture.
