CN concentration had a maximum in the summer, whereas the number concentrations of fine particles (D_p>0.3 μm) and coarse particles (D_p>2.0 μm) increased during the winter-spring. The range of CN concentration was 30-2200 cm^<-3> near the surface (surface-500 m) and 7-7250 cm^<-3> in the lower free troposphere (>1500 m). During the austral summer, higher CN concentration was often observed in the lower free troposphere. Frequent appearance of higher CN concentration in the free troposphere relative to the surface measurements strongly suggests that new particle formation in the Antarctic regions occurs in the lower free troposphere. Single particle analysis indicated that most of the aerosol particles during the winter were composed of Mg-enriched sea-salt particles originated from sea-salt fractionation on the sea-ice and their modified particles by NO_3^<-> and SO_4^<2->. This suggests that sea-salt fractionation on sea-ice and modification of sea-salt particles were affected greatly by aerosol hygroscopicity during the winter. Antarctic haze layer was observed not only in the boundary layer but also in the lower free troposphere.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00009582","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"551.5","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research, Research Organization of Information and Systems, Midori-cho 10-3, Tachikawa, Tokyo 190-8518."},{"subitem_text_language":"en","subitem_text_value":"Graduate School of Environmental Studies, Nagoya University, Furo-cho, Chikusa-ku, Nagoya 464-8601."},{"subitem_text_language":"en","subitem_text_value":"Graduate School of Environmental Studies, Nagoya University, Furo-cho, Chikusa-ku, Nagoya 464-8601."},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research, Research Organization of Information and Systems, Midori-cho 10-3, Tachikawa, Tokyo 190-8518."},{"subitem_text_language":"en","subitem_text_value":"Department of Earth System Science, Faculty of Science, Fukuoka University, 8-19-1 Nanakuma, Jonan-ku, Fukuoka, 814-0180."}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"情報・システム研究機構国立極地研究所"},{"subitem_text_value":"名古屋大学大学院環境学研究科"},{"subitem_text_value":"名古屋大学大学院環境学研究科"},{"subitem_text_value":"情報・システム研究機構国立極地研究所"},{"subitem_text_value":"福岡大学理学部地球圏科学科"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2010-12-28"}],"displaytype":"detail","filename":"KJ00007139359.pdf","filesize":[{"value":"10.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00007139359","url":"https://nipr.repo.nii.ac.jp/record/9582/files/KJ00007139359.pdf"},"version_id":"34ae645f-591c-45dc-ba54-45b18b882362"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"南極対流圏のエアロゾル鉛直分布とその季節変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"南極対流圏のエアロゾル鉛直分布とその季節変化"},{"subitem_title":"Seasonal variations and vertical features of aerosol particles in the Antarctic troposphere","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1161"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-12-28"},"publish_date":"2010-12-28","publish_status":"0","recid":"9582","relation_version_is_last":true,"title":["南極対流圏のエアロゾル鉛直分布とその季節変化"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:16:32.039880+00:00"}
