Plants give off odors after a rain. rain smells like fresh cut grass, earth and flowers...just like how a dogs smell gets stronger after they get wet (wet dog smell) so does everything else. Except the majority of things that get wet are plants and flowers so that smell overcomes most. Rain is a good smell! NikkiSixx Â· 8 years ago.
These oils collect in the soil and in rocks; rain then causes a range of smaller, volatile compounds within them to be released into the air. Their combination with geosmin in the air causes âpetrichorâ â the name given by scientists in 1964 to the smell after rain. The smell before rain, however, has a different cause. Particularly, the smell before a thunderstorm is a consequence of the electrical charge present in the atmosphere.
