The results showed that the CO_2 concentration decreased with height in an interval from the tropopause to 20-25km, and then became almost constant values above this level. The concentration differences between the lowermost part of the stratosphere and heights above 20-25km amounted to 4-8 ppmv. The lower stratospheric CO_2 showed different profiles for different measurements, probably due to annually- and seasonally-dependent poleward air transport and vertical mixing of stratospheric air near the jet stream. An average increase rate of the stratospheric CO_2 concentration was estimated to be 1.50 (±0.04) ppmv/year from the data above 20-25km. The CH_4 and N_2O concentrations decreased rapidly from about 1750 and 311 ppbv at the tropopause to 550-900 and 30-70 ppbv at 35km, respectively, due to their strong destruction through photolysis and chemical reactions. δ^<13>C value of CH_4 increased markedly with height, from -47‰ just above the tropopause to about -39‰ at 35km, which is quite opposite to the vertical profile of the CH_4 concentration. It was strongly suggested that the destruction of CH_4 by the reaction with Cl atoms is responsible for this steep vertical profile of δ^<13>C.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0167086000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東北大学理学部:宮城教育大学教育学部"},{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"東北大学理学部:国立環境研究所"},{"subitem_text_value":"東北大学理学部:国立極地研究所"},{"subitem_text_value":"東北大学理学部:資源環境技術総合研究所"},{"subitem_text_value":"東北大学理学部:国立極地研究所"},{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"菅原, 敏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中澤, 高清"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"青木, 周司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"町田, 敏暢"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森本, 真司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"村山, 昌平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"橋田, 元"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川村, 賢二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"本田, 秀之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 富造"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SUGAWARA, Satoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKAZAWA, Takakiyo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"AOKI, Shuji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MACHIDA, Toshinobu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MORIMOTO, Shinji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MURAYAMA, Shohei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HASHIDA, Gen","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWAMURA, Kenji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HONDA, Hideyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITOH, Tomizo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0167086.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0167086.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33182/files/SA0167086.pdf"},"version_id":"7a0c0cf3-6c45-4206-a329-ec9d9e0c0bab"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"クライオサンプリング装置","subitem_subject_scheme":"Other"},{"subitem_subject":"成層圏","subitem_subject_scheme":"Other"},{"subitem_subject":"二酸化炭素","subitem_subject_scheme":"Other"},{"subitem_subject":"メタン","subitem_subject_scheme":"Other"},{"subitem_subject":"一酸化二窒素","subitem_subject_scheme":"Other"},{"subitem_subject":"メタン炭素同位体比","subitem_subject_scheme":"Other"},{"subitem_subject":"日本","subitem_subject_scheme":"Other"}]},"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":"気球搭載クライオサンプリング装置を用いた成層圏大気中の CO_2,CH_4,N_2O の濃度と CH_4 の炭素同位体比の測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"気球搭載クライオサンプリング装置を用いた成層圏大気中の CO_2,CH_4,N_2O の濃度と CH_4 の炭素同位体比の測定"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"33182","relation_version_is_last":true,"title":["気球搭載クライオサンプリング装置を用いた成層圏大気中の CO_2,CH_4,N_2O の濃度と CH_4 の炭素同位体比の測定"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:13:32.494684+00:00"}
