Nitrogen oxides (NO x) are a key precursor in O3 formation. Although stringent
anthropogenic NO x emission controls have been implemented since the early 2000s in the …

Nitrogen oxides (NO x= NO+ NO2) are a primary component of air pollution—a leading
cause of premature death in humans and biodiversity declines worldwide. Although …

Fertilized soils have large potential for production of soil nitrogen oxide (NOx= NO+ NO2),
however these emissions are difficult to predict in high-temperature environments …

▪ Abstract Attaining the ambient standard for tropospheric ozone has been difficult in many
metropolitan areas, despite efforts to reduce anthropogenic sources of the ozone precursors …

EPA reports a steady decline of US anthropogenic NO x emissions in 2005–2019 summers,
while NO 2 vertical column densities (VCDs) from the OMI satellite over large spatial …

Soil nitrogen dioxide (NO X= NO 2+ NO) emissions have been measured and estimated to
be the second most significant contributor to the NO X burden following the fossil fuel …

Biogenic NO x emissions from soils are a large natural source with substantial uncertainties
in global bottom-up estimates (ranging from 4 to 15 Tg N yr− 1). We reduce this range in …

We examine the interannual variability in the NO 2 column over North America measured by
the Ozone Monitoring Instrument (OMI) in 2005–2008. By comparison to a model of soil NO …

Efforts to reduce tropospheric ozone (O3) pollution in the southeastern United States by
reducing emissions of volatile organic compounds have had only modest success, and …

Soil emissions represent~ 25% of the global annual atmospheric budget of nitrogen oxides
(NOx). The nitrogen isotopic composition of soil NOx emissions (δ15N‐NOx) is potentially …
