The results of the calculation with a cloud model having production process of ionization after gas release show that even the small production rate of ionization have the significant effect upon the life-time of the cloud. The recent observations of ionized clouds using ionsonde in a series of cesium and sodium release experiments with the rockets, K-9M-33, K-9M-39, K-9M-42 and K-9M-43, have cosistently suggested that total electron number in the cloud had increased with time after release owing to photo-ionization by solar U.V. radiation. The minimum scattering cross section of the cloud to make the positive signature in ionogram is 1.1-4.5 km2 at the altitude of 100km.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0124425000","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":"大阪市立大学工学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"堤, 四郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TSUTSUMI, Shiro","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":"SA0124425.pdf","filesize":[{"value":"437.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0124425.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31517/files/SA0124425.pdf"},"version_id":"9ce2d8ac-0815-4426-8c2f-6b46cfd1cd69"}]},"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":"超高層大気内電離雲による電波の後方散乱","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超高層大気内電離雲による電波の後方散乱"}]},"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":"31517","relation_version_is_last":true,"title":["超高層大気内電離雲による電波の後方散乱"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:57:46.902542+00:00"}
