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", "download_preview_message": "", "file_order": 0, "filename": "KJ00000035999.pdf", "filesize": [{"value": "757.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_6", "mimetype": "application/pdf", "size": 757300.0, "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"], "permalink_uri": "https://doi.org/10.15094/00004068", "pubdate": {"attribute_name": "公開日", "attribute_value": "1989-11-01"}, "publish_date": "1989-11-01", "publish_status": "0", "recid": "4068", "relation": {}, "relation_version_is_last": true, "title": ["Simultaneous observation of radar aurora and visible aurora over Mizuno Station"], "weko_shared_id": 4}
