The direction finding measurements have been made for these hiss-triggered chorus events. On the basis of the direction finding results and detailed analysis of the fine structures in the hiss band, we have suggested a generation model how a chorus is triggered by a hiss such that some coherent wavelets near the top of the hiss band phase-bunch electrons at the equator, and these phasebunched electrons radiate a coherent signal as they move away from the equator. Also, theoretical computations have been carried out in order to explain the df/dt, θ value (the polar angle between the wave normal direction and the Earth's magnetic field) and other factors by means of a two-dimensional ray-tracing method. The differences between the experimental and theoretical values are pointed out, and some possibilities to remedy these discrepancies are discussed.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004066","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10756224","subitem_source_identifier_type":"NCID"}]},"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/Research Institute of Atmospherics, Nagoya University/Department of Electrical and Electronic Engineering, Faculty of Engineering, Chiba University/Laboratoire de Physique et Chimie de l'Environment, CNRS/Laboratoire de Physique et Chimie de l'Environment, CNRS"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1989-11-01"}],"displaytype":"detail","filename":"KJ00000035997.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000035997","url":"https://nipr.repo.nii.ac.jp/record/4066/files/KJ00000035997.pdf"},"version_id":"fe8367fa-876c-4cd6-ade9-24cc92906210"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"GEOS-1 observation of hiss-triggered chorus emissions in the outer magnetosphere and their generation model","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"GEOS-1 observation of hiss-triggered chorus emissions in the outer magnetosphere and their generation model"}]},"item_type_id":"1","owner":"4","path":["538"],"pubdate":{"attribute_name":"公開日","attribute_value":"1989-11-01"},"publish_date":"1989-11-01","publish_status":"0","recid":"4066","relation_version_is_last":true,"title":["GEOS-1 observation of hiss-triggered chorus emissions in the outer magnetosphere and their generation model"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:24:17.132218+00:00"}
