Reactive nitrogen budget during the NASA SONEX Mission
(Wiley-Blackwell, 1999)
The SASS Ozone and Nitrogen Oxides Experiment (SONEX) over the North Atlantic during October/November 1997 offered an excellent opportunity to examine the budget of reactive nitrogen in the upper troposphere (8–12 km ...
OH and HO 2 chemistry in the North Atlantic free troposphere
(Wiley-Blackwell, 1999)
Interactions between atmospheric hydrogen oxides and aircraft nitrogen oxides determine the impact of aircraft exhaust on atmospheric chemistry. To study these interactions, the Subsonic Assessment: Ozone and Nitrogen Oxide ...
Ozone production in the upper troposphere and the influence of aircraft during SONEX: approach of NO x -saturated conditions
(Wiley-Blackwell, 1999)
During October/November 1997, simultaneous observations of NO, HO2 and other species were obtained as part of the SONEX campaign in the upper troposphere. We use these observations, over the North Atlantic (40–60°N), to ...
Origin of tropospheric NOx over subarctic eastern Canada in summer
(Wiley-Blackwell, 1994)
The origin of NOx in the summertime troposphere over subarctic eastern Canada is investigated by photochemical modeling of aircraft and ground-based measurements from the Arctic Boundary Layer Expedition (ABLE 3B). It is ...
Oxygenated volatile organic chemicals in the oceans: Inferences and implications based on atmospheric observations and air-sea exchange models
(Wiley-Blackwell, 2003)
Airborne measurements of oxygenated volatile organic chemicals (OVOC), OH free radicals, and tracers of pollution were performed over the Pacific during Winter/Spring of 2001. We interpret atmospheric observations of ...
Atmospheric Peroxyacetyl Nitrate (PAN): A Global Budget and Source Attribution
(Copernicus GmbH, 2014)
Peroxyacetyl nitrate (PAN) formed in the atmospheric oxidation of non-methane volatile organic compounds (NMVOCs) is the principal tropospheric reservoir for nitrogen oxide radicals \((NO_x = NO + NO_2)\). PAN enables the ...
Photochemistry of HOx in the upper troposphere at northern midlatitudes
(Wiley-Blackwell, 2000)
The factors controlling the concentrations of HO radicals (= OH + peroxy) in the upper troposphere (8–12 km) are examined using concurrent aircraft observations of OH, HO, HO, CHOOH, and CHO made during the Subsonic ...
