Today's Scent

I was recently given a challenge of how to represent the sense of smell - a hearty challenge because I consider smell to be indescribable.  We associate scents with things, colors, feelings, yet it's difficult to broaden the scope of a scent to an abstract.  But I'll give it my best shot.

Today's damp mist left a cool mustiness in the morning air, making the leaves dense with water and a smell like moss with a twang of anise in wet earth.  Add a dash of rusty brown copper like the smell of an old penny.  Finally, add the zest of a blood orange for a zing, just enough to sweeten the flavor.  What do you see in a scent today? - l.o.d.
