The results show that the MLT distribution of the magnetic variations shifts eastward or westward by a few hours in the latter case because the terrestrial magnetic field declines from the geographic meridian. Whether the distribution shifts eastward or westward depends on the longitude of the observatory. This fact suggests that whether the distribution of a phenomenon propagating along the terrestrial magnetic field is mainly determined in the magnetosphere or in the ionosphere may be determined by comparing the MLT distribution of the phenomenon's magnetic effect at observatories located at various longitudes.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006335","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":"AA11397422","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":"Graduate School of Science, Kyoto University/Graduate School of Science, Kyoto University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2001-09-01"}],"displaytype":"detail","filename":"KJ00000048075.pdf","filesize":[{"value":"626.5 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000048075","url":"https://nipr.repo.nii.ac.jp/record/6335/files/KJ00000048075.pdf"},"version_id":"e24d2fb0-fb37-44a2-a73f-ac1e4b4ce50a"}]},"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":"Longitudinal dependence of eastward and westward magnetic variations at mid-latitudes","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Longitudinal dependence of eastward and westward magnetic variations at mid-latitudes"}]},"item_type_id":"1","owner":"4","path":["805"],"pubdate":{"attribute_name":"公開日","attribute_value":"2001-09-01"},"publish_date":"2001-09-01","publish_status":"0","recid":"6335","relation_version_is_last":true,"title":["Longitudinal dependence of eastward and westward magnetic variations at mid-latitudes"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:02:54.109986+00:00"}
