Experimental evidence for the importance of convected methylhydroperoxide as a source of hydrogen oxide (HO x ) radicals in the tropical upper troposphere
(Wiley-Blackwell, 2001)
Concurrent measurements of OH, HO2, H2O2, and CH3OOH concentrations were made during an aircraft flight over the tropical South Pacific that followed a back-and-forth pattern at constant 10 km altitude for 4 hours. One end ...
Atmospheric chemistry in the Arctic and subarctic: Influence of natural fires, industrial emissions, and stratospheric inputs
(Wiley-Blackwell, 1992)
Haze layers with perturbed concentrations of trace gases, believed to originate from tundra and forest wild fires, were observed over extensive areas of Alaska and Canada in 1988. Enhancements of CH, CH, CH, CH, and CH ...
Summertime photochemistry of the troposphere at high northern latitudes
(Wiley-Blackwell, 1992)
The budgets of O, NO (NO+NO), reactive nitrogen (NO), and acetic acid in the 0–6 km column over western Alaska in summer are examined by photochemical modeling of aircraft and ground‐based measurements from the Arctic ...
Origin of ozone and NO x in the tropical troposphere: A photochemical analysis of aircraft observations over the South Atlantic basin
(Wiley-Blackwell, 1996)
The photochemistry of the troposphere over the South Atlantic basin is examined by modeling of aircraft observations up to 12-km altitude taken during the TRACE A expedition in September–October 1992. A close balance is ...
Latitudinal distribution of reactive nitrogen in the free troposphere over the Pacific Ocean in late winter/early spring
(Wiley-Blackwell, 1998)
The late winter/early spring (February/March, 1994) measurements of Pacific Exploratory Mission-West (PEM-W) B have been analyzed to show latitudinal distributions (45°N to 10°S) of the mixing ratios of reactive nitrogen ...
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 ...
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 ...
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 ...
