petrichor
noun·/ˈpɛt.rɪ.kɔːr/
The earthy, clean scent released when rain first strikes dry ground. Stone-dust, plant oils, and the promise of cooling air braided into one unmistakable aroma. Petrichor is specific to that first wet moment, the world turning new at the surface.
Petrichor rose from the sidewalk as the storm broke, and the city smelled briefly like a garden remembering itself.
Etymology
Formed from Greek petra "stone" + ichor, the fluid said to run in the veins of the gods. A modern coinage with myth-minded naming: rain waking earth into a scent worthy of legend.
