Short summary

Various sources and meteorological conditions affect the short-term variation in NH₃ concentrations in the urban atmosphere. An analysis of 2 years of hourly data suggests that mist evaporation and stomata exchange of tree leaves after the effects of bird droppings engenders a rapid increase in NH₃ concentrations. Emissions from urban tree canopies are a new mode of passing reactive nitrogen that has never before been described as an important source in the literature.
