Interactive comment on “Formation of Reactive Nitrogen Oxides from Urban Grime Photochemistry” by A. M. Baergen and D. J. Donaldson
نویسنده
چکیده
Manuscript by Alyson Baergen and D. J. Donaldson focuses on formation of HONO, a key chemical species and/or reaction intermediate in atmospheric chemistry, during photolysis of urban grime. Given the fact that sources and formation of daytime HONO in urban setup are poorly understood, this study reveals potential chemical and photochemical reaction pathways and mechanisms to yield HONO. The knowledge gained in this study will lead and redirect the scientists studying urban atmosphere to closely look at heterogeneous photochemistry of urban grime. Authors present scientific results from a series of experiments, in a combined approach of Incoherent Broad Band Cavity Enhanced Spectroscopy (IBBCES) and Quartz Crystal Microbalance (QCM), to clearly support their major conclusions on photochemical production of HONO and wa-

Interactive comment on “Formation of Reactive Nitrogen Oxides from Urban Grime
It is believed that the deposition of NOy (mainly HNO3, even if N2O5 is also discussed here) is a sink process for NOx, however this study challenges this point of view and demonstrates, for the time, that photochemistry of photochemistry of urban grime is as a potential source of gaseous nitrous acid (HONO). This has been suggested before but never demonstrated. This study therefore a nice pie...
متن کاملFormation of Reactive Nitrogen Oxides from Urban Grime Photochemistry
Impervious surfaces are ubiquitous in urban environments and constitute a substrate onto which atmospheric 10 constituents can deposit and undergo photochemical and oxidative processing, giving rise to “urban grime” films. HNO3 and N2O5 are important sinks for NOx in the lower atmosphere and may be deposited onto these films, forming nitrate through surface hydrolysis. Although such deposition ...
متن کاملA Reactivity Based Emission Inventory for the South Pars and Its Implication for Ozone Pollution Control
The South Pars zone in Iran encompasses the largest gas refineries and petrochemical complexes in the world. In the South Pars zone, elevated concentrations of reactive hydrocarbons co-emitted with nitrogen oxides from industrial facilities lead to substantial ozone production downwind. To understand the role of these emissions on the ozone formation and, to formulate appropriate control st...
متن کاملOzone production chemistry in the presence of urban plumes.
Ozone pollution affects human health, especially in urban areas on hot sunny days. Its basic photochemistry has been known for decades and yet it is still not possible to correctly predict the high ozone levels that are the greatest threat. The CalNex_SJV study in Bakersfield CA in May/June 2010 provided an opportunity to examine ozone photochemistry in an urban area surrounded by agriculture. ...
