Petrichor — “The pleasant smell that accompanies the first rain after a dry spell.”
“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.”
via the outstanding Aron Walker, who’s currently teaching chemistry for the peace corps, and who just saw Tanzania’s first rains.
