Anatomy of Summertime Upslope Events in Northeastern Colorado: Ammonia (NH₃) Transport to the Rocky Mountains.

ABSTRACT: The Transport and Transformation of Ammonia (TRANS²Am) airborne field campaign occurred over northeastern Colorado during the summers of 2021 and 2022. A subset of the TRANS²Am flights investigated easterly wind conditions capable of moving agricultural emissions of ammonia (NH₃) through urban areas and into the Rocky Mountains. TRANS²Am captured 6 of these events, unveiling important commonalities. (1) NH₃ enhancements are present over the mountains on summer afternoons when easterly winds are present in the foothills region. (2) The abundance of gas-phase NH₃ is 1 and 2 orders of magnitude higher than particle-phase NH₄⁺ over the mountains and major agricultural sources, respectively. (3) During therm
