The energy parameters of primary electrons are derived by using measured intensities at 844.6nm (OI) and 670.5nm (N_21PG) from a multi-channel photometer observation at Syowa Station, Antarctica, in 1990. It is shown that each auroral type has its own relationship between energy parameters of precipitating electrons. In a discrete aurora, downward electron energy flux generally varied proportionally with square of average energy. This tendency can be identified as an ohmic-like feature. This special relation is accounted for by a theory in which electrons are accelerated by a field-aligned-potential difference. We also found that in some discrete auroras, precipitating electrons did not show the ohmic-like behavior. These exceptional cases are thought to be caused by two factors. One is a geometric relation between auroral arcs and the field of view of the photometer. The other is the change of the L-E-L constant in the magnetosphere (M. FRIDMAN and J. LEMAIRE; J. Geophys. Res., 85,664,1980) due to temporal variations of plasma parameters, such as electron density and thermal energy in the source region of the auroral particles.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008818","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":"Faculty of Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Faculty of Science, University of Tokyo"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京大学理学部"},{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"東京大学理学部"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1993-11-01"}],"displaytype":"detail","filename":"KJ00000140117.pdf","filesize":[{"value":"973.5 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000140117","url":"https://nipr.repo.nii.ac.jp/record/8818/files/KJ00000140117.pdf"},"version_id":"b1546d46-9d02-432e-b5df-0c0349bc15fd"}]},"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":"地上光学観測による降下電子エネルギーパラメータの特性及び 加速機構推定への応用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"地上光学観測による降下電子エネルギーパラメータの特性及び 加速機構推定への応用"},{"subitem_title":"Evaluation of energy parameters of auroral electrons by using photometric observations and its application to investigate a generation mechanism","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1106"],"pubdate":{"attribute_name":"公開日","attribute_value":"1993-11-01"},"publish_date":"1993-11-01","publish_status":"0","recid":"8818","relation_version_is_last":true,"title":["地上光学観測による降下電子エネルギーパラメータの特性及び 加速機構推定への応用"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:09:32.682355+00:00"}
