Impulsive noises of 2～50μV/m at 31kc/s (&lrtri;f=1kc/s) observed by K-9 M-6 seem to be realbut their origin is not clear. Noise level at about 100 kc/s seems to be less than 1μV/m at &lrtri;f=1kc/s in the ionosphere up to 350km. Radio noises in the ionosphere and Galactic emissions were observed at 3 0 Mc/s by L-3H-1. The noise in the ionosphere was maximum near the critical plasma layer at which the equivalent noise temperature was about 10^<70>K (0.2 μV/m at &lrtri;f=1kc/s), if the noise is due to electromagnetic waves This result is consistent with the excess noises recorded in the measurements of the Galaxy by rockets and satellites in USA and UK. These noises in the MF band, however may be attributed to the electrostatic field of thermal or nonthermal plasma oscillations","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0124933000","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":"東京天文台"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高倉, 達雄"}],"nameIdentifiers":[{"nameIdentifier":"406581","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TAKAKURA, Tatsuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"406582","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0124933.pdf","filesize":[{"value":"281.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0124933.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31874/files/SA0124933.pdf"},"version_id":"4ec54567-a0fb-4a3b-83e7-bbb815b5899d"}]},"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":"電離層内の長波,中波帯電波雑音および銀河電波の観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"電離層内の長波,中波帯電波雑音および銀河電波の観測"}]},"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":"31874","relation_version_is_last":true,"title":["電離層内の長波,中波帯電波雑音および銀河電波の観測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:47:53.399716+00:00"}
