The attenuation coefficients around the Sør Rondane Mountains, Antarctica were mapped from the 179MHz airborne radio-echo sounder, which made observations during 1986. The map shows a tendency of decreasing attenuation as the surface altitude of the ice sheet increases. This result is interpreted by using the relationship between attenuation coefficients and ice temperature. In addition, a cosine relationship was found between attenuation coefficients and the angle of the radar polarization from the topographic contour. The dynamic range of the variety of the attenuation coefficients is 1.2dB/100m. If the ice flow is perpendicular to the topographic contour, the ice flow direction will be derived from the polarimetric radar observation.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003997","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":"AA10756213","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":"Communications Research Laboratory, Ministry of Posts and Telecommunications"},{"subitem_text_language":"en","subitem_text_value":"Communications Research Laboratory, Ministry of Posts and Telecommunications"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ABSTRACT"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1997-11-01"}],"displaytype":"detail","filename":"KJ00001014960.pdf","filesize":[{"value":"73.1 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00001014960","url":"https://nipr.repo.nii.ac.jp/record/3997/files/KJ00001014960.pdf"},"version_id":"dff839f4-4731-4d9f-ada3-e9b54677681a"}]},"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":"CHARACTERISTICS OF RADIO ATTENUATION COEFFICIENT ON THE SØR RONDARNE ICE SHEET, ANTARCTICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"CHARACTERISTICS OF RADIO ATTENUATION COEFFICIENT ON THE SØR RONDARNE ICE SHEET, ANTARCTICA"}]},"item_type_id":"1","owner":"4","path":["535"],"pubdate":{"attribute_name":"公開日","attribute_value":"1997-11-01"},"publish_date":"1997-11-01","publish_status":"0","recid":"3997","relation_version_is_last":true,"title":["CHARACTERISTICS OF RADIO ATTENUATION COEFFICIENT ON THE SØR RONDARNE ICE SHEET, ANTARCTICA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:25:22.235007+00:00"}
