The measurement system required 100 mlSTP of an atmospheric air sample, corresponding to approximately 0.18μlSTP of CH_4, to determine the δ^(13)CH_4 value with a reproducibility of 0.07‰. Replicated analyses of a CH_4-in-air standard gas during the period from 2002 to 2008 indicated that the value of δ^(13)CH_4 measured by this system was consistent within the measurement reproducibility. To evaluate the δ^(13)CH_4 measurement system, thus developed, diurnal variations of the atmospheric CH_4 concentration and δ^(13)CH_4 were observed in the northern part of the Tokyo metropolitan area. From the relationship between the CH_4 concentration and δ^(13)CH_4, dominant sources of the observed CH4 fluctuations were identified.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00009483","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, Kaga 1-chome, Itabashi-ku, Tokyo 173-8515."},{"subitem_text_language":"en","subitem_text_value":"Center for Atmospheric and Oceanic Studies, Graduate School of Science, Tohoku University, 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, Aramaki, Aoba-ku, Sendai 980-8578."}]},"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":"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"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2009-03-30"}],"displaytype":"detail","filename":"KJ00005231259.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00005231259","url":"https://nipr.repo.nii.ac.jp/record/9483/files/KJ00005231259.pdf"},"version_id":"b0ef2327-e4a8-4270-a5e0-0ed1b1ac1c4d"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"連続フロー式質量分析計を用いた大気中メタンの炭素同位体比の高精度測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"連続フロー式質量分析計を用いた大気中メタンの炭素同位体比の高精度測定"},{"subitem_title":"High precision measurements of carbon isotopic ratio of atmospheric methane using a continuous flow mass spectrometer","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1155"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-03-30"},"publish_date":"2009-03-30","publish_status":"0","recid":"9483","relation_version_is_last":true,"title":["連続フロー式質量分析計を用いた大気中メタンの炭素同位体比の高精度測定"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:16:59.727559+00:00"}
