It has been found that the new DF can determine localized exits of VLF auroral hiss with an accuracy of about 10°. A comparison of the DF results with the ground-based auroral data has shown that impulsive type auroral hiss with a wide-band frequency range has not emerged from the whole region of bright aurora but from some localized regions of bright electron auroras at the ionospheric level, and that the arrival directions of auroral hiss change rapidly in accordance with the auroral movements.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008201","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":"Research Institute of Atmospherics, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"名古屋大学空電研究所"},{"subitem_text_value":"国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1981-01-01"}],"displaytype":"detail","filename":"KJ00000139417.pdf","filesize":[{"value":"15.8 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000139417","url":"https://nipr.repo.nii.ac.jp/record/8201/files/KJ00000139417.pdf"},"version_id":"99a5d232-75d6-4d05-8c53-33c1ec5bf053"}]},"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":"極域におけるオーロラヒス放射の到来方向測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"極域におけるオーロラヒス放射の到来方向測定"},{"subitem_title":"Direction finding of auroral VLF hiss in auroral zone","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["977"],"pubdate":{"attribute_name":"公開日","attribute_value":"1981-01-01"},"publish_date":"1981-01-01","publish_status":"0","recid":"8201","relation_version_is_last":true,"title":["極域におけるオーロラヒス放射の到来方向測定"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:26:05.026996+00:00"}
