The region where the averaged phase shift between the north-south and the east-west components has some finite value appeared systematically around the auroral oval, indicating an existence of the hydromagnetic wave component of comparable magnitude with the magnetic fluctuation generated by small-scale field-aligned currents. The low frequency waves (0.125-0.25Hz) showed left-handed polarization (L-mode) and the amplitude was around 5-10nT. On the other hand, the R-mode waves dominated in 1.0-2.0Hz range and the amplitude was estimated to be about 1nT.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004043","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":"AA10756224","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":"Data Analysis Center for Geomagnetism and Spacemagnetism,Faculty 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":"1988-02-01"}],"displaytype":"detail","filename":"KJ00000035889.pdf","filesize":[{"value":"872.4 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000035889","url":"https://nipr.repo.nii.ac.jp/record/4043/files/KJ00000035889.pdf"},"version_id":"4a94b032-5d25-4d0e-a607-2a1cd558adab"}]},"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":"A statistical study of ULF waves observed by MAGSAT at ionospheric altitude","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A statistical study of ULF waves observed by MAGSAT at ionospheric altitude"}]},"item_type_id":"1","owner":"4","path":["537"],"pubdate":{"attribute_name":"公開日","attribute_value":"1988-02-01"},"publish_date":"1988-02-01","publish_status":"0","recid":"4043","relation_version_is_last":true,"title":["A statistical study of ULF waves observed by MAGSAT at ionospheric altitude"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:24:36.358783+00:00"}
