In the article "The Scent of Snow" by Aubrey Allison, they discuss the intricacies of the question "Does Snow have a Scent" and their claim suggests that snow does not necessarily have a smell and says that humidity helps our noses smell, in cold temperatures odor molecules don’t travel far, and fewer of them make their way into our cold-numbed noses, but they do not provide any sources for their claim throughout that paragraph. However a quick Google search shows that they aren't lying about this, multiple sources like PBS, NASA, and Hyper air all generalize this statement as true.
Furthermore, in the second half of the article, Aubrey speaks about how The smell of snow, in some ways, is made up of the scent of our snowy environment: pine and fir trees; the environmental smells influence the way snow may smell, which almost contradictory to the first half of what the article is talking, even though that is somewhat true, but However again this statement is also true, having two true contradictory statements is not very credible when trying to talk your point.
