Increases and expansion of anthropogenic emissions of both oxidized nitrogen compounds, NOx, and a reduced nitrogen compound, NH3, have driven an increase in nitrogen deposition. We estimate global NOx and NH3 emissions and use a model of the global troposphere, MOGUNTIA, to examine the pre-industrial and contemporary quantities and spatial patterns of wet and dry NOy and NHx deposition. Pre-industrial wet plus dry NOx and NHx deposition was greatest for tropical ecosystems, related to soil… 
Physical and biogeochemical controls over terrestrial ecosystem responses to nitrogen deposition
Anthropogenic perturbations to the global nitrogen (N) cycle nowexceed those to any other major biogeochemical cycle on Earth, yet ourability to predict how ecosystems will respond to the rapidly
Atmospheric N Deposition Increases Organic N Loss from Temperate Forests
Atmospheric deposition of nitrogen (N) resulting from fossil fuel combustion has increased N inputs to temperate forests worldwide with large consequences for forest productivity and water quality.
THE ATMOSPHERIC NITROGEN BUDGET OVER THE SOUTH AFRICAN HIGHVELD
Molecular nitrogen is a highly abundant element in the atmosphere; it is stable and not very reactive. Anthropogenic activities have caused greater concentrations of nitrogencontaining compounds that
Nitrogen deposition and its ecological impact in China: an overview.
A first record of bulk atmospheric deposition patterns of major ions in southern South America
Despite the importance of long-term atmospheric deposition of ions for vegetation productivity and biogeochemistry, southern South America lacks long-term deposition records. We report a 6-year-long
Atmospheric inorganic nitrogen in wet deposition to a red soil farmland in Southeast China, 2005–2009
AimsBiological processes in agro-ecosystems have been affected by atmospheric nitrogen (N) deposition, but there is uncertain of the N deposition fluxes and associated variations. This study aimed to
EXAMINING THE SOURCES AND TRANSPORT OF REACTIVE NITROGEN EMISSIONS USING STABLE ISOTOPES TECHNIQUES
Reactive nitrogen (Nr) emissions (i.e., NOx, HNO3, and NH3) from the transportation and electricity-generating sectors are declining due to increasingly stringent air quality regulations and
