The ionospheric attenuations for VLF whistler mode and HF waves (as a CNA value) are calculated by using full-wave analysis to evaluate their correlations for various ionospheric electron density profiles enhanced by precipitating electrons. The calculation results show negative correlations between CNA and VLF whistler mode waves in accordance with the observation results. Then, the gradient of the negative correlation becomes larger with decreasing altitude of maximum electron density. Thus, we found that the correlation provides information on the vertical profile of the enhanced electron density in the lower ionosphere caused by electron precipitation. This allows the study of electron precipitation in the daytime, in addition to Trimpi events at nighttime.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00009496","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":"Institute of Science and Engineering, Kanazawa University, Kakuma-machi, Kanazawa 920-1192."},{"subitem_text_language":"en","subitem_text_value":"Institute of Science and Engineering, Kanazawa University, Kakuma-machi, Kanazawa 920-1192."},{"subitem_text_language":"en","subitem_text_value":"Kanazawa University, Kakuma-machi, Kanazawa 920-1192."},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research, Research Organization of Information and Systems, Midori-cho 10-3, Tachikawa-City Tokyo 190-8518."},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research, Research Organization of Information and Systems, Midori-cho 10-3, Tachikawa-City Tokyo 190-8518."}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"金沢大学理工研究域電子情報学系"},{"subitem_text_value":"金沢大学理工研究域電子情報学系"},{"subitem_text_value":"金沢大学"},{"subitem_text_value":"情報・システム研究機構国立極地研究所"},{"subitem_text_value":"情報・システム研究機構国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2009-07-30"}],"displaytype":"detail","filename":"KJ00005592279.pdf","filesize":[{"value":"622.7 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00005592279","url":"https://nipr.repo.nii.ac.jp/record/9496/files/KJ00005592279.pdf"},"version_id":"7aecb199-08c0-4e32-8bd0-5b056aca5694"}]},"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":"自然VLF放射強度と銀河雑音電波吸収(CNA)の相関関係を用いた下部電離層電子密度の推定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"自然VLF放射強度と銀河雑音電波吸収(CNA)の相関関係を用いた下部電離層電子密度の推定"},{"subitem_title":"Estimation of enhanced electron density in the lower ionosphere using correlation between natural VLF emission intensity and CNA","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1156"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-07-30"},"publish_date":"2009-07-30","publish_status":"0","recid":"9496","relation_version_is_last":true,"title":["自然VLF放射強度と銀河雑音電波吸収(CNA)の相関関係を用いた下部電離層電子密度の推定"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:20:48.408241+00:00"}
