Sources and sinks of formic, acetic, and pyruvic acids over central Amazonia: 2. Wet season
(Wiley-Blackwell, 1990)
We have determined the gas phase concentrations of formic (HCOOH), acetic (CH3COOH), and pyruvic (CH3C(O)COOH) acids in the forest canopy, boundary layer, and free troposphere over the central Amazon Basin during the ...
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 ...
The atmospheric sulfur cycle over the Amazon Basin: 2. Wet season
(Wiley-Blackwell, 1990)
We determined the fluxes and concentrations of atmospheric sulfur species at ground level and from aircraft over the Amazon Basin during the 1987 wet season, providing a comprehensive description of the sulfur cycle over ...
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 ...
