Let's Abandon the "High NOₓ" and "Low NOₓ" Terminology
Abstract
"High-NOₓ" and "low-NOₓ" are used ubiquitously in the atmospheric chemistry community as shorthand terms meant to describe the chemical end-member photochemical conditions that span from "urban"/"anthropogenically-impacted" to "remote"/"pristine". They do not, however, have precise or accepted definitions. Following a rather heated discussion at the 2012 Atmospheric Chemistry Mechanism conference in Davis, California, I was tasked with suggesting appropriate definitions. I've come to the opinion that these terms cause more confusion than they do insight and we should abandon them entirely.

Additional Information
This essay was originally published in issue 50 of IGAC News (July, 2013). A decade later, I feel it is still relevant. I advocate that as authors, reviewers, and editors we work to weed out the high and low NOx terminology from our manuscripts. Reprinted with permission of IGAC News.
