The characteristics are caused by a significant gradient of electron density inside the Es layer. We employ a new analysis method for accurate estimation of the electron temperature and density. It also allows us to obtain the temperature and density in a shorter time interval than the voltage sweep period. Our new observation and analysis method provide us with first detailed structure of electron density and temperature inside the Es layer with an unprecedented spatial resolution. The maximum electron density and the minimum electron temperature observed inside Es layer are estimated to be 9.7×10(exp 5) cm-3 and 550 K, respectively, at an altitude of 98 km. The total thickness of the layer is about 1 km. Furthermore, the detailed trend of the electron temperature from its boundary toward the center of Es layer was revealed so clearly owing to the new method. Electron temperature in the surrounding region of the Es layer is found to be quite high, suggesting significant heating at the altitude range. The observed reduction of electron temperature in the Es layer embedded in an elevated temperature region is interpreted in terms of dependence of heat sources and cooling processes on the thermal electron density.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: 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 illustrations","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1830006000","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-18-002E","subitem_description_type":"Other"}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20637/JAXA-RR-18-002E/0001","subitem_identifier_reg_type":"JaLC"}]},"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_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2216","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東海大学"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究所太陽系科学研究系(JAXA)(ISAS)"},{"subitem_text_value":"東海大学"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokai University"},{"subitem_text_language":"en","subitem_text_value":"Department of Solar System Sciences, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"},{"subitem_text_language":"en","subitem_text_value":"Tokai University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"坂本, 優美花"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"阿部, 琢美"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三宅, 亙"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakamoto, Yumika","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Abe, Takumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miyake, Wataru","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":"2020-01-31"}],"displaytype":"detail","filename":"AA1830006000.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1830006000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/1800/files/AA1830006000.pdf"},"version_id":"78729317-d2a7-4c2d-9612-14709c1587a8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ionosphere","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sporadic E layer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Electron density","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Electron temperature","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sounding rocket","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Energy budget","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Detailed Structure of Electron Temperature and Density inside the Sporadic E Layer","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Detailed Structure of Electron Temperature and Density inside the Sporadic E Layer","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["23","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-10-25"},"publish_date":"2018-10-25","publish_status":"0","recid":"1800","relation_version_is_last":true,"title":["Detailed Structure of Electron Temperature and Density inside the Sporadic E Layer"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:38:56.122191+00:00"}
