In order to obtain the global distribution of atmospheric CH_4,air samples were collected on board at intervals of about 5°in latitude between Tokyo and Syowa Station late in 1987 and 1988,and CH_4 was measured by a GC-FID method. Latitudinal variations of atmospheric CH_4,including the observations late in 1984 (M. HIROTA et al. : Proc. NIPR Symp. Polar Meteorol. Glaciol., 1,69,1987), are summarized as follows : 1. Mixing ratios decreased gradually from 30°N to ITCZ, and steeply at the ITCZ by 3-5%. 2. Locations of the ITCZ from the cloud images of the GMS agreed with the places where mixing ratios of methane decreased steeply from north to south. 3. South of the ITCZ, mixing ratios were almost constant to Syowa Station. Their mean values and standard deviations were 1.578 and 0.008 ppm in 1984,1.611 and 0.012 ppm in 1987,and 1.627 and 0.008 ppm in 1988. The average increase rate of these mean values was 12 ppb/year from 1984 to 1988. 4. Small latitudinal variations (±10-15 ppb) were observed late in 1987 and 1988 in the Southern Hemisphere. 4-1. Small minimum south of the ITCZ. 4-2. Broad maximum around 30-40°S.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003664","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10756213","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Marine Department, Japan Meteorological Agency"},{"subitem_text_language":"en","subitem_text_value":"Meteorological Research Institute"},{"subitem_text_language":"en","subitem_text_value":"Meteorological Research Institute"},{"subitem_text_language":"en","subitem_text_value":"Upper Atmosphere and Space Research Laboratory, Faculty of Science, Tohoku University"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ABSTRACT"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1991-05-01"}],"displaytype":"detail","filename":"KJ00000767867.pdf","filesize":[{"value":"100.6 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000767867","url":"https://nipr.repo.nii.ac.jp/record/3664/files/KJ00000767867.pdf"},"version_id":"ca0b000b-9997-4250-b9ac-5174777a0ac4"}]},"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":"MEASUREMENT OF ATMOSPHERIC METHANE BETWEEN TOKYO AND SYOWA STATION","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MEASUREMENT OF ATMOSPHERIC METHANE BETWEEN TOKYO AND SYOWA STATION"}]},"item_type_id":"1","owner":"4","path":["528"],"pubdate":{"attribute_name":"公開日","attribute_value":"1991-05-01"},"publish_date":"1991-05-01","publish_status":"0","recid":"3664","relation_version_is_last":true,"title":["MEASUREMENT OF ATMOSPHERIC METHANE BETWEEN TOKYO AND SYOWA STATION"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:30:43.221339+00:00"}
