It is found that the ionospheric exit from which the narrow-band auroral hiss comes out is usually located in the lower latitude side than the position of quiet auroral arcs. These results demonstrate that the propagation path of auroral hiss is deviated from the geomagnetic field lines along which auroral particles precipitate. Therefore, it is concluded that the waves propagate downwards to the ionosphere in a non-ducted mode. Comparing the location of the ionospheric exit of auroral hiss with the ratio of 8kHz hiss intensity at Syowa to that at Mizuho, it is estimated that the loss rate of auroral hiss is, on the average, 2-3 dB/100km with respect to the horizontal direction.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008283","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":"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":"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":"1982-02-01"}],"displaytype":"detail","filename":"KJ00000139497.pdf","filesize":[{"value":"7.6 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000139497","url":"https://nipr.repo.nii.ac.jp/record/8283/files/KJ00000139497.pdf"},"version_id":"380dd8e8-7ebc-4988-8649-ea17d5580d20"}]},"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":"昭和基地における狭帯域オーロラヒス放射の到来方向観測結果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"昭和基地における狭帯域オーロラヒス放射の到来方向観測結果"},{"subitem_title":"Arrival direction finding for narrow-band auroral hiss at Syowa Station","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["980"],"pubdate":{"attribute_name":"公開日","attribute_value":"1982-02-01"},"publish_date":"1982-02-01","publish_status":"0","recid":"8283","relation_version_is_last":true,"title":["昭和基地における狭帯域オーロラヒス放射の到来方向観測結果"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:29:52.317105+00:00"}
