Journal ArticleDOI
Significant geographic gradients in particulate sulfate over Japan determined from multiple-site measurements and a chemical transport model: Impacts of transboundary pollution from the Asian continent
Masahide Aikawa,Toshimasa Ohara,Takatoshi Hiraki,Okihiro Oishi,Akihiro Tsuji,Makiko Yamagami,Kentaro Murano,Hitoshi Mukai +7 more
TL;DR: In this paper, the authors found a significant geographic gradient (longitudinal and latitudinal) in sulfate (SO42−) concentrations measured at multiple sites over the East Asian Pacific Rim region.
Journal ArticleDOI
Chemistry of Fog Water Collected in the Mt. Rokko Area (Kobe City, Japan) between April 1997 and March 2001
TL;DR: Fog chemistry was studied for four years (April 1997-March 2001) at Mt. Rokko (altitude 931 m) in Kobe, Japan as mentioned in this paper, and the correlation of the concentrations of the components in fog water indicated that (NH4)2SO4 and/or NH4HSO4 were involved in the formation of fog drops in the atmosphere.
Journal ArticleDOI
Separate chemical characterizations of fog water, aerosol, and gas before, during, and after fog events near an industrialized area in Japan
TL;DR: Fog water, aerosol, and gas were separately collected at Mt. Rokko (altitude 931m) in Kobe, Japan, using a new sampling method at a mountainous site near a highly industrialized area.
Journal ArticleDOI
Washout/rainout contribution in wet deposition estimated by 0.5 mm precipitation sampling/analysis
Masahide Aikawa,Takatoshi Hiraki +1 more
TL;DR: In this paper, a precipitation dataset collected on a 0.5mm precipitation basis was studied, and the parameters analyzed in this study were the pH (i.e., H+ concentration), electric conductivity (EC), and S O 4 2− and N O 3 − concentrations.
Journal ArticleDOI
A method for simple and accurate estimation of fog deposition in a mountain forest using a meteorological model
TL;DR: In this article, the authors applied a meteorological model to investigate fog occurrence, acidification and deposition in mountain forests, the model was modified to calculate fog deposition accurately by the simple linear function of fog deposition onto vegetation derived from numerical experiments using the detailed multilayer atmosphere-vegetation-soil model.
