Diurnal CO_2 variation was hardly observable throughout the year. The secular CO_2 trend was variable with time, showing slow increase in 1984,1986 and 1988 and rapid increase in 1985 and 1987. The annual CO_2 increase was remarkable, especially in 1987,which may have been related to the 1987 ENSO event. The average rate of annual CO_2 increase over the last 5 years was about 1.6ppmv yr^<-1>. The average seasonal CO_2 cycle showed minimum and maximum concentrations in mid-April and in early October, respectively. Its peak-to-peak amplitude was about 1.1ppmv for the period 1984-1988. The seasonal cycle was variable from year to year, but there was no indication of long-term amplitude increase. It was found that irregular CO_2 variations with amplitudes of about 0.2ppmv and with periods of a few tens of days have high correlation with air mass exchange by synoptic scale weather disturbances.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008967","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 Atmosphetic and Oceanic Studies, Faculty of Science, Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"Center for Atmosphetic and Oceanic Studies, Faculty of Science, Tohoku University"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東北大学理学部大気海洋変動観測研究センター"},{"subitem_text_value":"東北大学理学部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":"1997-03-01"}],"displaytype":"detail","filename":"KJ00000140316.pdf","filesize":[{"value":"487.2 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000140316","url":"https://nipr.repo.nii.ac.jp/record/8967/files/KJ00000140316.pdf"},"version_id":"103d94e3-cb60-4c56-a50a-97f1e95f3f4a"}]},"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":"昭和基地における大気中の二酸化炭素濃度の連続観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"昭和基地における大気中の二酸化炭素濃度の連続観測"},{"subitem_title":"Continuous measurement of atmospheric CO2 concentration at Syowa Station","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1116"],"pubdate":{"attribute_name":"公開日","attribute_value":"1997-03-01"},"publish_date":"1997-03-01","publish_status":"0","recid":"8967","relation_version_is_last":true,"title":["昭和基地における大気中の二酸化炭素濃度の連続観測"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:13:49.590432+00:00"}
