ARMSTRONG et al. (Planet. Space Sci., 25,1193,1977) with Fourier analysis using computer assisted programing of the data. This method was applied to 30MHz riometer data observed at Tjornes (from 8 September 1984 to 30 September 1986) and Husafell (from 15 August 1985 to 31 August 1986) in Iceland. The QDCs are usefull in studying the diurnal, seasonal and solar cycle variations of average ionospheric absorption level.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004103","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10756224","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"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1991-06-01"}],"displaytype":"detail","filename":"KJ00000036034.pdf","filesize":[{"value":"819.0 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036034","url":"https://nipr.repo.nii.ac.jp/record/4103/files/KJ00000036034.pdf"},"version_id":"405b4506-d6ac-44a8-b93a-972c62cf4630"}]},"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":"CNA quiet day curves and their sidereal time dependence","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"CNA quiet day curves and their sidereal time dependence"}]},"item_type_id":"1","owner":"4","path":["540"],"pubdate":{"attribute_name":"公開日","attribute_value":"1991-06-01"},"publish_date":"1991-06-01","publish_status":"0","recid":"4103","relation_version_is_last":true,"title":["CNA quiet day curves and their sidereal time dependence"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:23:51.751128+00:00"}
