The frequency of the upper hybrid resonance and the impedance value, of the spherical probe with radius of 6cm, at 406KHz are automatically detected in this instrumental system. The results of the measurement are summalized in forms of the data tables and the data plots, after the calculation of the ionosheric parameters, namely, electron number density and the sheath capacitance of the probe. The data obtained for about 160 full path coverage reveal various aspects of the low latitude ionoshere and protonoshere. Preliminary results of the data analysis give informations on the local time dependency of the ionospheric structure. In the nighttime observation of the ionosphere, peculiarly distributed irregularities are often observed ; the irregular structures are prevaded over about several hundreds of kilometer or more along the satellite path. Sometimes rarefaction events aries in the electron number density. The rarefaction seems to be limited in the neighborhood of the satellite. The possible mechanism for the rarefaction is the charging of the satellite surface and the probe being caused by the high energy particle precipitation related to the south atlantic anomaly of the magnetic field, and the magnetic equator.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0124797000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"東北大学理学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高橋, 忠利"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森岡, 昭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大家, 寛"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAHASHI, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MORIOKA, A.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OYA, H.","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":"2020-01-23"}],"displaytype":"detail","filename":"SA0124797.pdf","filesize":[{"value":"779.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0124797.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31756/files/SA0124797.pdf"},"version_id":"50470859-f6ce-424a-abc5-4ec25efff495"}]},"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":"\"たいよう\"IMPによる低緯度電離層の観測結果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"\"たいよう\"IMPによる低緯度電離層の観測結果"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"31756","relation_version_is_last":true,"title":["\"たいよう\"IMPによる低緯度電離層の観測結果"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:51:35.250481+00:00"}
