Ammonia Deposition in Rocky Mountain National Park

The use of the term "nitrogen particles" in this video is likely to be misleading. What they're referring to are both atmospheric aerosols -- dust and other particulates -- as well as precipitation that has nitrogen-compound components. Some of these compounds dissolve in water, so precipitation carries them; some stick to dust; some clump into aerosols themselves.

Nitrogen itself, of course, is the odorless, colorless gas that makes up about 80% of the atmosphere in the form of nitrogen molecules (N2). The animation here suggests that there's something like N6 that exists as a particle. If that's thought of as a cartoon rather than the real thing, and if nitrogen as a component of precipitation and aerosols is understood, then this discussion is spot on.

Of course, it's not just RMNP that's getting the nitrogen, it's the entire Front Range high country. RMNP makes a great laboratory to study this impact on ecosystems on much larger scales. HPH
