@article{oai:nagoya.repo.nii.ac.jp:00020269, author = {TAKAGI, Masumi and IWATA, Akira and KANADA, Masahiro and TORIYAMA, Noriji}, journal = {Proceedings of the Research Institute of Atmospherics, Nagoya University}, month = {Mar}, note = {Observations, made at Hachijo-Jima in the early winter, of atmospheric electrical conductivity, aerosol number densities in Aitken- and Mie-size ranges, and concentrations of radon, ozone, and nitrogen oxides are described. The representative values of the above items were 10.0 x 10^-15 s/m, 1.47 x 10^3 cm^-3, 39.4 cm^-3, 28 pCi/m^3, 71 ppb, and 3.0 ppb, respectively. These values and the ranges of distribution show that the atmosphere on Hachijo-Jima is in an intermediate state between the coastal area of the mainland Japan and the mid-ocean. The values observed in the air, which blows in from the sea and probably not much disturbed by pollution of island origin, are near the midocean values. The highest conductivity and the lowest aerosol density were observed in the rain in the sea wind. A few items observed some days showed remarkable daily variations which possibly correspond to weather conditions.}, pages = {21--34}, title = {AEROSOL OBSERVATION AT HACHIJO-JIMA IN EARLY WINTER}, volume = {29}, year = {1982} }
