When this paper was first published Figure 5 was incorrect. The publisher regrets this oversight. The complete page with correct figure and original pagination is printed overleaf.
Characteristics of reactive nitrogen compounds and other relevant trace gases in the atmosphere at urban and rural areas of Korea during May–June, 2004
Journal of Atmospheric Chemistry - Tập 58 - Trang 203-218 - 2007
This study examines the general characteristics of reactive nitrogen oxides (NOy) at urban and rural sites in terms of measurement- and modeling-based analyses. In this field study, NOx at urban and rural sites were 92 and 89% of NOy on average, respectively. HONO levels (e.g., 1.8 ppbv) at the urban site were significantly higher than those at the rural site by a factor of 4.5. HONO concentration......
The effects of below-cloud aerosol on the acidification process of rain
Journal of Atmospheric Chemistry - Tập 17 - Trang 157-178 - 1993
Using a model of the acidification process of rain, we calculate and analyze the effects and contributions of a below-cloud aerosol in its different concentrations and acidities on the pH and ion components of rain (SO

Chemical ionisation mass spectrometer for measurements of OH and Peroxy radical concentrations in moderately polluted atmospheres
Journal of Atmospheric Chemistry - - 2009
A new version of an atmospheric pressure chemical ionisation mass spectrometer has been developed for ground based in situ atmospheric measurements of OH and total peroxy (HO2 + organic peroxy) radicals. Based on the previously developed principle of chemical conversion of OH radicals to H2SO4 in reaction with SO2 and detection of H2SO4 using an ion molecule reaction with NO

Fate of 1,3-dioxolane in the troposphere: kinetics, mechanism with theoretical support, and atmospheric implications
Journal of Atmospheric Chemistry - - 2023
The atmospheric fate of 1,3-dioxolane is assessed by measuring the OH and Cl initiated gas-phase oxidation kinetics, and exploring their mechanistic pathways. Absolute OH reaction rate coefficient of 1,3-dioxolane using laser photolysis-laser induced fluorescence technique is found to be (1.27 ± 0.03) × 10–11 cm3 molecule−1 s−1 at 298 ± 2 K and it is in good agreement with the measured relative va......
Near UV absorption spectra and photolysis products of difunctional organic nitrates: Possible importance as NO x reservoirs
Journal of Atmospheric Chemistry - Tập 17 - Trang 353-373 - 1993
Difunctional organic nitrates are important products of the atmospheric reaction of NO3 radicals with unsaturated hydrocarbons about which relatively little is known. In a continuation of the investigation of the atmospheric chemistry of such compounds, the UV absorption spectra of the following organic dinitrates and keto nitrates have been quantitively measured in the gas phase at 298±2 K and at......
Rainwater Chemistry and Wet Deposition over the Equatorial Forested Ecosystem of Zoétélé (Cameroon)
Journal of Atmospheric Chemistry - Tập 46 - Trang 173-198 - 2003
Within the framework of IDAF (IGAC DEBITS AFRICA: International GlobalAtmospheric Chemistry/DEposition of Biogeochemically Important TraceSpecies/Africa) network, data analysis is realised on precipitation chemical composition collected in Zoétélé, in Southern Cameroon. This station, located atabout 200 km from the Atlantic Ocean, is representative of a so-called `Evergreen Equatorial Forest' ecos......
Characteristics, loss and gain of atmospheric carbonyl compounds in winters of 2008–2010 in Pearl River Delta region, China
Journal of Atmospheric Chemistry - Tập 70 - Trang 53-67 - 2013
Formaldehyde (HCHO), acetaldehyde (CH3CHO) and acetone (CH3COCH3) were measured at Wanqingsha (WQS) in south China during November-December 2008–2010. Carbonyl compound pollution characteristics under the influence of the financial crisis (FC) were studied. Atmospheric carbonyl compound concentrations in the 2008 and 2009 sampling periods were affected by the 2008 FC. The industrial downturn plus ......
