The VLF instrument onboard Akebono measures plasma waves below 20 kHz and plays an important role to study plasma physics in the Earth's magnetosphere. The VLF measures not only wave spectrum in digital format but also analogue waveform, and the analogue waveform data are transmitted via analogue telemetry. Huge amount of analogue data have been stored, but data analyses are not comprehensively performed so far because of the difficulties of their peculiar characteristics. In the present paper, we introduce current status of data analysis system developed for the VLF analogue waveform data. We also address anticipated outcomes from these huge datasets.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1530026004","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-RR-14-009","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1113","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1192675X","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"金沢大学"},{"subitem_text_value":"金沢大学"},{"subitem_text_value":"金沢大学"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kanazawa University"},{"subitem_text_language":"en","subitem_text_value":"Kanazawa University"},{"subitem_text_language":"en","subitem_text_value":"Kanazawa University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"笠原, 禎也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"後藤, 由貴"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大池, 悠太"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kasahara, Yoshiya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Goto, Yoshitaka","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oike, Yuta","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"AA1530026004.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1530026004.pdf","url":"https://jaxa.repo.nii.ac.jp/record/1918/files/AA1530026004.pdf"},"version_id":"7939cd59-ff18-4f64-b620-7bc9825ec68a"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"あけぼの衛星アナログ広帯域受信器による観測データの自動較正法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"あけぼの衛星アナログ広帯域受信器による観測データの自動較正法"}]},"item_type_id":"3","owner":"1","path":["66","1404","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-04-20"},"publish_date":"2015-04-20","publish_status":"0","recid":"1918","relation_version_is_last":true,"title":["あけぼの衛星アナログ広帯域受信器による観測データの自動較正法"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:32:28.325562+00:00"}
