Erik gifted me a new word, in response to the post about rain just below.

I think that word needs a post all of its own ... Petrichor.

petrichor (PET-ri-kuhr) noun

The pleasant smell that accompanies the first rain after a dry spell.

[From petro- (rock), from Greek petros (stone) + ichor (the fluid that is supposed to flow in the veins of the gods in Greek mythology). Coined by researchers I.J. Bear and R.G. Thomas.]

"Petrichor, the name for the smell of rain on dry ground, is from oils given off by vegetation, absorbed onto neighboring surfaces, and released into the air after a first rain." Matthew Bettelheim; Nature's Laboratory; Shasta Parent (Mt Shasta, California); Jan 2002.

"But, even in the other pieces, her prose breaks into passages of lyrical beauty that come as a sorely needed revivifying petrichor amid the pitiless glare of callousness and cruelty." Pradip Bhattacharya; Forest Interludes;; Jul 29, 2001.
