The experiment has provided us with global characteristics of ionospheric photoelectrons and also of energetic particles over a wide range of latitude, longitude, altitude (350-850km) and local time. The precipitation of auroral particles are observed at latitudes higher than the trapping boundary of higher-energy particles. The electron precipitation pattern is diffuse in the dayside auroral region, whereas it is quite discrete in the nightside. The ion energy distribution is found to be generally harder than the corresponding electrons. Energetic electrons with energies of 10-100keV are also found out at dusk hours near the equator. The photoelectron energy distribution is shown to have a peak at 20-30eV and also a sharp cutoff near 60eV. However, the shape of structure at 20-30eV is found to have a significant variation depending on latitude, longitude and local time. A large peak at 20-30eV is observed occasionally over the South-Atlantic anomaly region.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166671000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"神戸大学工学部"},{"subitem_text_value":"神戸大学工学部"},{"subitem_text_value":"神戸大学工学部"},{"subitem_text_value":"神戸大学工学部"},{"subitem_text_value":"神戸大学工学部"},{"subitem_text_value":"神戸大学工学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"向井, 利典"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"賀谷, 信幸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"久保, 治也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松本, 治弥"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 富造"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平尾, 邦雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MUKAI, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAYA, N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KUBO, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MATSUMOTO, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITO, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HIRAO, K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0166671.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166671.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32877/files/SA0166671.pdf"},"version_id":"43d06fa9-1dde-445d-9340-84e826814541"}]},"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":"「大空」による低エネルギー荷電粒子の観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"「大空」による低エネルギー荷電粒子の観測"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32877","relation_version_is_last":true,"title":["「大空」による低エネルギー荷電粒子の観測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:21:45.631692+00:00"}
