I'm part of a volunteer group that surveys bird populations at a nearby watershed/estuary. Last Monday I went with that group to Old Woman Creek in Ohio and I stood out front of the main building in the prairie that they had burned the week prior. It was wet and the ground was completely saturated; it had been raining for days. And even though the ground was cold and waterlogged, it still smelled like this odd, sweet smoke. I've only ever smelled cigarette and campfire smoke before, which is empty and light, and very ashy. This was different, and caught me off guard. I don't know how to parse the difference persay, but this smelled full and rounded and heavy, even though there was no smoke in the air, just the lingering scent, like when smoke pervades something and hangs onto it, even once the actual ash cloud is long gone.
