A sea-state based source function for size- and composition-resolved marine aerosol production
source function size- and composition-resolved marine aerosol production
2011/2/25
A parameterization for the size- and composition-resolved production fluxes of nascent marine aerosol was developed from prior experimental observations and extrapolated to ambient conditions based on...
Ozone production during the field campaign RISFEX 2003 in the sea of Japan: analysis of sensitivity and behaviour based on an improved indicator
Ozone production the field campaign RISFEX 2003 the sea of Japan an improved indicator
2010/10/21
The ratio Φ=kHC+OH[HC]/kNOx+OH[NOx] is used as an indicator for the sensitivity of ozone production (P(O3)) to HC and NOx in the field campaign RISFEX 2003 (RIShiri Fall EXperiment 2003) at Rishiri Is...
Laboratory simulation for the aqueous OH-oxidation of methyl vinyl ketone and methacrolein: significance to the in-cloud SOA production
Laboratory simulation the aqueous OH-oxidation methyl vinyl ketone the in-cloud SOA production
2010/10/11
Increasing evidence suggests that secondary organic aerosol (SOA) is formed through aqueous phase reactions in atmospheric clouds. In the present study, the aqueous oxidation of methyl vinyl ketone (M...
Impact of Manaus City on the Amazon Green Ocean atmosphere: ozone production, precursor sensitivity and aerosol load
Manaus City the Amazon Green Ocean atmosphere ozone production precursor sensitivity aerosol load
2010/10/11
We used a Single Column Chemistry and Transport Model (SCM) to infer the urban pollution emission fluxes of Manaus City, implying observed mixing ratios of CO, NOx and VOC. The model can reproduce the...
The production and persistence of ΣRONO2 in the Mexico City plume
ΣRONO2 the Mexico City plume
2010/8/16
Alkyl and multifunctional nitrates (RONO2, ΣANs) have been observed to be a significant fraction of NOy in a number of different chemical regimes. Their formation is an important free radical chain te...
Influence of relative humidity and temperature on the production of pinonaldehyde and OH radicals from the ozonolysis of α-pinene
relative humidity and temperature pinonaldehyde and OH radicals α-pinene
2010/8/16
The ozonolysis of α-pinene has been investigated under dry and humid conditions in the temperature range of 243–303 K. The results provided new insight into the role of water and temperature in the de...
Impact of West African Monsoon convective transport and lightning NOx production upon the upper tropospheric composition: a multi-model study
West African Monsoon NOx production the upper tropospheric composition a multi-model study
2010/8/13
Within the African Monsoon Multidisciplinary Analysis (AMMA), we investigate the impact of nitrogen oxides produced by lightning (LiNOx) and convective transport during the West African Monsoon (WAM) ...
Cross-hemispheric transport of central African biomass burning pollutants: implications for downwind ozone production
Cross-hemispheric transport central African biomass burning pollutants downwind ozone production
2010/8/12
Pollutant plumes with enhanced concentrations of trace gases and aerosols were observed over the southern coast of West Africa during August 2006 as part of the AMMA wet season field campaign. Plumes ...

Secondary organic aerosol (SOA) production was observed at significant levels in a series of modern diesel exhaust (DE) aging experiments conducted at the European Outdoor Photoreactor/Simulation Cham...
Inferring ozone production in an urban atmosphere using measurements of peroxynitric acid
Inferring ozone production urban atmosphere peroxynitric acid
2009/6/16
Observations of peroxynitric acid (HO2NO2) obtained simultaneously with those of NO and NO2 provide a sensitive measure of the ozone photochemical production rate. We illustrate this technique for con...
