Nighttime records represent irregular phase and amplitude fluctuations and sometimes involve quasi-sinusoidal fluctuations. The phase and amplitude change associated with cosmic noise absorption (CNA) are observed on the VLF signals, for which the phase is advanced with the change of the electron number density distribution of lower ionosphere.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Faculty of Education, Hirosaki University/National Institute of Polar Research/National Institute of Polar Research/Radio Research Laboratories/Geophysics Research Laboratory, Faculty of Science, University of Tokyo"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1986-08-01"}],"displaytype":"detail","filename":"KJ00000012544.pdf","filesize":[{"value":"673.4 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012544","url":"https://nipr.repo.nii.ac.jp/record/1990/files/KJ00000012544.pdf"},"version_id":"157bce65-5755-43b0-bd0e-03e413cddbe4"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"A case study of VLF phase and amplitude variation at 12.1 kHz (Aldra) in Iceland","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A case study of VLF phase and amplitude variation at 12.1 kHz (Aldra) in Iceland","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["396"],"pubdate":{"attribute_name":"公開日","attribute_value":"1986-08-01"},"publish_date":"1986-08-01","publish_status":"0","recid":"1990","relation_version_is_last":true,"title":["A case study of VLF phase and amplitude variation at 12.1 kHz (Aldra) in Iceland"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:54:48.126981+00:00"}
