Impact of Front Range sources on reactive nitrogen concentrations and deposition in Rocky Mountain National Park.

ABSTRACT: Human influenced atmospheric reactive nitrogen (RN) is impacting ecosystems in Rocky Mountain National Park (ROMO). Due to ROMO's protected status as a Class 1 area, these changes are concerning, and improving our understanding of the contributions of different types of RN and their sources is important for reducing impacts in ROMO. In July-August 2014 the most comprehensive measurements (to date) of RN were made in ROMO during the Front Range Air Pollution and Photochemistry Éxperiment (FRAPPÉ). Measurements included peroxyacetyl nitrate (PAN), C₁-C₅ alkyl nitrates, and high-time resolution NO_x, NO_y, and ammonia. A limited set of measurements was extended through October. Co-located measurements of a suite of volatile organic compounds provide i
