The relationship between observed stratospheric δ^<15>N of N_2, δ^<18>O of O_2 and δ(Ar N_2) over the Svalbard Islands and Barrow showed mass-dependent fractionation of atmospheric components in the stratosphere, which suggested that gravitational separation could be observable in the lowermost stratosphere inside the polar vortex. By examining the rates of change in δ(O_2 Nv) and δ^<13>C of CO_2 relative to the CO_2 concentration, such observed correlations were bound to be mainly attributable to upward propagation of their seasonal cycles produced in the troposphere and height-dependent air age as well as gravitational separation in the stratosphere. Air samples collected over Syowa Station, Antarctica, Kiruna, Sweden and Sanriku, Japan using balloon-borne cryogenic air samplers were analyzed for δ^<15>N of Nv and δ^<18>O of O_2. Strength of the gravitational separation was a function of latitude, showing the largest separation inside the polar vortex over Kiruna. It is suggested that information on increase of gravitational separation with height is useful in understanding the vertical transport of air masses in the stratosphere. By comparing the gravitational separations, mean age of air and N_2O concentration at two height intervals with N_2O concentrations > 125 ppb and < 45 ppb, the effect of descending air was found to be more significant over Kiruna than over Syowa Station and Sanriku. The variation in the gravitational separation with height is found to be weaker in the region with N_2O concentrations between 45 and 125 ppb than in other regions, which might suggest that vertical mixing of air occurred in this region.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00009565","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":"Center for Atmospheric and Oceanic Studies, Graduate School of Science, Tohoku University, 6-3 Aoba, Aramaki, Aoba-ku, Sendai 980-8578."},{"subitem_text_language":"en","subitem_text_value":"Miyagi University of Education, 149 Aoba, Aramaki, Aobaku, Sendai 980-0845."},{"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":"Center for Atmospheric and Oceanic Studies, Graduate School of Science, Tohoku University, 6-3 Aoba, Aramaki, Aoba-ku, Sendai 980-8578."},{"subitem_text_language":"en","subitem_text_value":"Japan Agency for Marine-Earth Science and Technology, 3173-25 Showa-machi, Kanazawa-ku, Yokohama, Kanagawa, 236-0001."},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency, Institute of Space and Astronautical Science (ISAS), 3-1-1 Yoshinodai, Chuo-ku, Sagamihara, Kanagawa, 252-5210."},{"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."}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東北大学大学院理学研究科大気海洋変動観測研究センター"},{"subitem_text_value":"宮城教育大学"},{"subitem_text_value":"情報・システム研究機構国立極地研究所"},{"subitem_text_value":"東北大学大学院理学研究科大気海洋変動観測研究センター"},{"subitem_text_value":"海洋研究開発機構"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究所"},{"subitem_text_value":"情報・システム研究機構国立極地研究所"}]},"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":"KJ00007136519.pdf","filesize":[{"value":"4.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00007136519","url":"https://nipr.repo.nii.ac.jp/record/9565/files/KJ00007136519.pdf"},"version_id":"2cbdd39c-46d6-4ee3-bd50-da5e871ff5d8"}]},"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":"北極航空機観測計画(AAMP02)と南極昭和基地,スウェーデン・キルナおよび日本三陸上空における成層圏大気採取実験によって観測された 大気主要成分の重力分離","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"北極航空機観測計画(AAMP02)と南極昭和基地,スウェーデン・キルナおよび日本三陸上空における成層圏大気採取実験によって観測された 大気主要成分の重力分離"},{"subitem_title":"Gravitational separation of major atmospheric components observed in the stratosphere over Syowa Station, Antarctica, Kiruna, Sweden and Sanriku, Japan.","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":"9565","relation_version_is_last":true,"title":["北極航空機観測計画(AAMP02)と南極昭和基地,スウェーデン・キルナおよび日本三陸上空における成層圏大気採取実験によって観測された 大気主要成分の重力分離"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:16:47.311996+00:00"}
