It was also found that the variation of the electric field was dominantly seen in the dawn-to-dusk (Ey) component while less variation was observed in the noon-midnight (Ex) component. Most electron precipitations were found in a region where a divE was negative. The integrated energy flux of the precipitating electrons was in the range from 0.01(erg/(cm)^2s) to 1(erg/(cm)^2s), which can produce auroral luminosity in the polar cap region. Though we have no simultaneous image data right now, it is likely that Akebono traversed multiple sun-aligned arcs.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008852","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":"551.510.535/.537","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":"The Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"The Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"The Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"The Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"The Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"The Institute of Space and Astronautical Science"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"文部省宇宙科学研究所"},{"subitem_text_value":"文部省宇宙科学研究所"},{"subitem_text_value":"文部省宇宙科学研究所"},{"subitem_text_value":"文部省宇宙科学研究所"},{"subitem_text_value":"文部省宇宙科学研究所"},{"subitem_text_value":"文部省宇宙科学研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1994-07-01"}],"displaytype":"detail","filename":"KJ00000140161.pdf","filesize":[{"value":"290.4 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000140161","url":"https://nipr.repo.nii.ac.jp/record/8852/files/KJ00000140161.pdf"},"version_id":"f0fc7621-3867-42a9-a261-ec399c212bfd"}]},"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":"あけぼの衛星観測によって明らかにされた極冠域における降下電子と電場の関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"あけぼの衛星観測によって明らかにされた極冠域における降下電子と電場の関係"},{"subitem_title":"Relation of electric field and particle precipitation in the polar cap region inferred from Akebono observations","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1108"],"pubdate":{"attribute_name":"公開日","attribute_value":"1994-07-01"},"publish_date":"1994-07-01","publish_status":"0","recid":"8852","relation_version_is_last":true,"title":["あけぼの衛星観測によって明らかにされた極冠域における降下電子と電場の関係"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:10:30.439120+00:00"}
