The diurnal variations in field strength were not found at the equinox, but in other months the field strength dropped after sunset. The night-time signals at Syowa Station were received mainly through the long path on the great circle. The mode of propagation varies with the condition of the ionosphere, and the mixed mode (e. g. E plus F layer reflection waves) is often predominant. At the main phase of sudden commencement of magnetic storm, the field strength abruptly drops, and this effect must be taken into consideration for the operation of communications. For the purpose of experimental studies of the radio communication in high latitudes, it is planned to continue the field strength measurement on the routine basis in the future.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00007683","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"62(*2)","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Radio Research Laboratories"},{"subitem_text_language":"en","subitem_text_value":"Radio Research Laboratories"},{"subitem_text_language":"en","subitem_text_value":"Radio Research Laboratories"},{"subitem_text_language":"en","subitem_text_value":"Radio Research Laboratories"},{"subitem_text_language":"en","subitem_text_value":"Yamagawa Radio Wave Ovservatory, Radio Research Laboratories"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"電波研究所電波部"},{"subitem_text_value":"電波研究所電波部"},{"subitem_text_value":"電波研究所電波部"},{"subitem_text_value":"電波研究所電波部"},{"subitem_text_value":"電波研究所山川電波観測所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1972-11-01"}],"displaytype":"detail","filename":"KJ00002476683.pdf","filesize":[{"value":"3.3 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002476683","url":"https://nipr.repo.nii.ac.jp/record/7683/files/KJ00002476683.pdf"},"version_id":"b4ac8291-802c-4de0-a104-d79d2802de17"}]},"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":"南極昭和基地における短波伝搬実験結果(日本南極地域観測隊の報告)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"南極昭和基地における短波伝搬実験結果(日本南極地域観測隊の報告)"},{"subitem_title":"Experimental Results of the HF Propagation at Syowa Station, Antarctica (Reports of the Japanese Antarctic Research Expedition)","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["951"],"pubdate":{"attribute_name":"公開日","attribute_value":"1972-11-01"},"publish_date":"1972-11-01","publish_status":"0","recid":"7683","relation_version_is_last":true,"title":["南極昭和基地における短波伝搬実験結果(日本南極地域観測隊の報告)"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T11:53:22.292005+00:00"}
