Most people enjoy the scent of rain when it starts to fall. That is called petrichor, and you can read about it here. But I never really thought about the smell of snow before because it is usually so cold that it is hard to smell anything. So I was interested to read this story from the Washington Post about how the smell of snow is changing due to rising temperatures, which are changing the blend of impurities in the air that give snow its smell. Apparently snow has a variety of smells depending on what the contaminants are. So next time we get snow, take a sniff and see what is contributing to the smell of snow in your area.
