| Research Abstract |
To investigate and verify the chemical components provided by long range transportation with solid precipitation processes, some observations were carried out at Ny-Aelesund as a sufficient remote area from sources by collections of solid precipitation particles, aerosol particles and gases. Snow particles without riming were observed to contain Less and more of SO42- and NO3-, respectively, brought by northwesterly wind from arctic sea ice covering fields than those with riming by southeasterly wind from open sea area in the north end of Gulf stream. It may be remarked that these observational results are coincident with those of some laboratory experiments and most recent observations of fresh snow and environmental atmosphere in polar regions.
