Interactive comment on “Atmospheric reactive nitrogen concentrations at ten sites with contrasting land use in an arid region of Central Asia” by K. H. Li et al

General Comments: This manuscript, “Atmospheric reactive nitrogen concentrations at ten sites with contrasting land use in an arid region of Central Asia”, is a good baseline assessment of the concentrations of nitrogenous species for an understudied region of the world, the arid Xinjiang region of China. This study will provide foundational information in understanding air quality over this region. That being said, there is nothing particularly novel or noteworthy about the study, it is a simple assessment of the region. In addition, it is quite short, so it’s difficult to ascertain its potential impact. However, these types of baseline studies are still important in contemporary ecological sciences.
