petrichor
PET-rih-kor
The distinctive scent released when rain falls on dry earth — an earthy, mineral sweetness produced by oils from plants absorbed into soil and rock, released by the impact of raindrops and mixed with geosmin from soil bacteria. The smell of the land greeting rain after a long absence.
Etymology
Greek petra (stone) + ichor (the fluid that flows in the veins of the gods). Coined in 1964 by Australian mineralogists Isabel Bear and Richard Thomas. The blood of stone.
