The budget of reactive nitrogen (Nr; oxidized and reduced inorganic and organic forms of
nitrogen) has at least doubled since the preindustrial era due to human activities. Excess Nr …

Under the influence of human activities and the rapid development of industry and
agriculture, atmospheric nitrate (NO− 3) pollution is becoming increasingly serious and has …

Global change influences biogeochemical cycles within and between environmental
compartments (ie, the cryosphere, terrestrial and aquatic ecosystems, and the atmosphere) …

Oxygen isotope anomaly of nitrate aerosol (∆ 17O-NO3−) contributes to understanding the
atmospheric nitrogen chemistry in the polar oceans. Here,∆ 17O-NO3− of the aerosol …

Nitrous acid (HONO) is an important precursor to hydroxyl radical (OH) that determines
atmospheric oxidative capacity and thus impacts climate and air quality. Wildfire is not only a …

Atmospheric samples collected during 2017 and 2018 Chinese Arctic Expedition cruises are
used to investigate the latitudinal gradients of nitrate (NO3−) sources and production in the …

Abstract Atmospheric nitrate (NO3−= particulate NO3−+ gas‐phase nitric acid [HNO3]) and
sulfate (SO42−) are key molecules that play important roles in numerous atmospheric …

Surface snow and atmospheric samples collected along a traverse from the coast to the ice
sheet summit (Dome A) are used to investigate summertime atmospheric production of …

Chemical characterization of hurricane wet deposition is integral to understanding how
future extreme weather events will impact coastal biogeochemical cycles. Sequential …

The photolysis of snowpack nitrate (NO3–) is an important source of gaseous reactive
nitrogen species that affect atmospheric oxidants, particularly in remote regions. However, it …
