Distribution and fate of selected oxygenated organic species in the troposphere and lower stratosphere over the Atlantic
(Wiley-Blackwell, 2000)
A large number of oxygenated organic chemicals (peroxyacyl nitrates, alkyl nitrates, acetone, formaldehyde, methanol, methylhydroperoxide, acetic acid and formic acid) were measured during the 1997 Subsonic Assessment ...
Satellite observations of formaldehyde over North America from GOME
(Wiley-Blackwell, 2000)
Formaldehyde (HCHO) is an important indicator of tropospheric hydrocarbon emissions and photochemical activity. We present HCHO observations over North America for July 1996 from the GOME instrument on-board the ESA ERS-2 ...
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 ...
General circulation model assessment of direct radiative forcing by the sulfate-nitrate-ammonium-water inorganic aerosol system
(Wiley-Blackwell, 2001)
An on-line simulation of aerosol sulfate, nitrate, ammonium, and water in the Goddard Institute for Space Studies general circulation model (GCM II-prime) has been used to estimate direct aerosol radiative forcing for the ...
Continental sources, transoceanic transport, and interhemispheric exchange of carbon monoxide over the Pacific
(Wiley-Blackwell, 2001)
The Pacific Exploratory Mission to the Tropics phase B (PEM-Tropics B) aircraft campaign in March-April 1999 surveyed the chemical composition of the Pacific atmosphere from 35°N to 35°S and up to 12 km altitude. We use ...
Atmospheric budget of acetone
(Wiley-Blackwell, 2002)
The atmospheric budget and distribution of acetone are investigated by using a priori estimates of sources and sinks to constrain a global three-dimensional atmospheric model simulation and then using atmospheric observations ...
Constraints from 210 Pb and 7 Be on wet deposition and transport in a global three-dimensional chemical tracer model driven by assimilated meteorological fields
(Wiley-Blackwell, 2001)
The atmospheric distributions of the aerosol tracers 210Pb and 7Be are simulated with a global three-dimensional model driven by assimilated meteorological observations for 1991–1996 from the NASA Goddard Earth Observing ...
Transport and scavenging of soluble gases in a deep convective cloud
(Wiley-Blackwell, 2000)
A one-dimensional entraining/detraining plume model is used to examine the transport and scavenging of soluble gases in tropical deep convection. The model is applied to a continental system observed over Brazil during the ...
Atmospheric hydrogen cyanide (HCN): Biomass burning source, ocean sink?
(Wiley-Blackwell, 2000)
The observed seasonal amplitude of atmospheric HCN concentrations implies an atmospheric lifetime of only a few months for HCN, much shorter than is commonly assumed from oxidation by OH (a few years). We propose that ocean ...
