The radar aurora was observed by a 50MHz Doppler radar at Syowa Station while the visible aurora was monitored by a zenith photometer (4278 A) with a view angle of about 7° at Mizuho Station, 270km south-east of Syowa. It is found that within the bright auroral arc the radar echo intensity (therefore, the ionospheric electric field) is suppressed. Strong echoes caused by the gradient-drift instability appeared between the arcs. Within the faint, diffuse-like aurora which followed the bright arcs, the radar echoes due to the two-stream plasma instability driven by the electric field exceeding 25mV/m were detected.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004068","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":"Communications Research Laboratory/National Institute of Polar Research/National Institute of Polar Research/Communications Research Laboratory/Communications Research Laboratory"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1989-11-01"}],"displaytype":"detail","filename":"KJ00000035999.pdf","filesize":[{"value":"757.3 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000035999","url":"https://nipr.repo.nii.ac.jp/record/4068/files/KJ00000035999.pdf"},"version_id":"dcb988be-28ee-4602-b226-819e3bdbc4f3"}]},"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":"Simultaneous observation of radar aurora and visible aurora over Mizuno Station","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Simultaneous observation of radar aurora and visible aurora over Mizuno Station"}]},"item_type_id":"1","owner":"4","path":["538"],"pubdate":{"attribute_name":"公開日","attribute_value":"1989-11-01"},"publish_date":"1989-11-01","publish_status":"0","recid":"4068","relation_version_is_last":true,"title":["Simultaneous observation of radar aurora and visible aurora over Mizuno Station"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:24:14.916337+00:00"}
