elucidate temporal variations of greenhouse gases and their related gases in the Arctic and Antarctic regions and to investigate their sources and sinks, systematic measurements of atmospheric CO_2, CH_4CO, N_2O, O_2 and tropospheric O_3 concentrations have been carried out at Syowa Station, Antarctica and Ny-Alesund, Svalbard. The CO_2 concentrations at both polar sites have increased at a rate of about 1.9 ppmv yr^<-1>, reflecting fossil fuel combustion and land use change. The CH_4 concentrations also showed clear seasonal cycles superimposed on complex secular trends. The increase rate of the CH_4 concentration varied with time. CH_4 increases were observed until 1999, the concentrations remained steady from 2000 to 2006 and then rapid increases were observed in 2007. Stable isotope data of CH_4 revealed causes of the seasonal cycles and the secular variations of the CH_4 concentrations. The O_2 concentrations (δ(O_2 N_2)) at both polar sites showed prominent seasonal cycles and secular decreasing trends. From analyses of the Atmospheric Potential Oxygen (APO) and CO_2 concentrations, the CO_2 uptake rates by the terrestrial biosphere and the ocean were estimated to be 1.1 and 2.7 GtC yr^<-1>, respectively. By comparing the N_2O concentrations observed at Ny-Alesund and numerical model results, it was suggested that the observed seasonal N_2O cycle could be enlarged by intrusion of a stratospheric air mass with low N_2O concentration into the troposphere in summer. With an analysis using a three dimensional chemical-transport model and the CO concentration at Syowa Station, sporadic increases of CO concentration observed in February-March, 2003 and February, 2007 were ascribed to CO release by large-scale forest fires in Australia. Surface ozone depletion events were observed more than 40 times at Syowa Station from 1988 to 2007.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00009563","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, Midoricho 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 Agency for Marine-Earth Science and Technology, 3173-25 Showa-machi, Kanazawa-ku, Yokohama, Kanagawa, 236-0001."},{"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":"National Institute of Polar Research, Research Organization of Information and Systems, Midoricho 10-3, Tachikawa, Tokyo 190-8518."},{"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":"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":"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":"National Institute of Polar Research, Research Organization of Information and Systems, Midoricho 10-3, Tachikawa, Tokyo 190-8518."}]},"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":"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":"海洋研究開発機構"},{"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":"情報・システム研究機構国立極地研究所"},{"subitem_text_value":"宮城教育大学"},{"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":"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":"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":"KJ00007136419.pdf","filesize":[{"value":"12.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00007136419","url":"https://nipr.repo.nii.ac.jp/record/9563/files/KJ00007136419.pdf"},"version_id":"717a6106-2488-49d0-afa1-1ab34b31d0d2"}]},"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":"南北両極域における大気中の温室効果気体と関連気体の変動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"南北両極域における大気中の温室効果気体と関連気体の変動"},{"subitem_title":"Temporal variations of atmospheric greenhouse gases and their related gases at Syowa Station, Antarctica and Ny-Alesund, Svalbard.","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":"9563","relation_version_is_last":true,"title":["南北両極域における大気中の温室効果気体と関連気体の変動"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:16:49.028663+00:00"}
