Does the rain smell?
Often preceded by rain, the air has a characteristic, somewhat earthy smell to it. This smell may be from soil bacteria that produce aromatic gases. As rain falls on the soil, it drives these gases into the air, where the wind carries them ahead of the sky.

Yes, the smell of rain is called "petrichor." It's caused by the release of compounds produced by soil-dwelling bacteria and plants when rain hits the ground.
