I would like to compare the smell of air in the spring with the smell of air in the winter. Unfortunately, it's spring now for me and I can only experience what the spring air is like. I know there's this kind of distinct "scent" in the winter that I can't completely describe. That scent occurs when it is very cold and you've just left the warmth of your house. I never thought winter air would be very important, so I never wrote anything down. Could anyone help me? Thanks.
