There are no pronounced seasonal variations in abundance, the peak height and the width of the sodium layer. No enhancement of aboundance in winter has been observed, which is different from those obtained at mid-latitudes in the northern hemisphere. It is, however, interesting to show the oscillatory variation in abundance with a period of about 40 days. The nocturnal variations of sodium profile show wave-like structure with a vertical wavelength of 10 to 16km and a period of 4 to 8h, which suggests the existence of gravity wave. During sodium lidar measurements under auroral activity, it has been observed by chance that the layer is disturbed by auroral break-up associated with the change of cosmic noise absorption (CNA).","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003539","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":"Faculty of Engineering, Shinshu University"},{"subitem_text_language":"en","subitem_text_value":"Water Research Institute, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Upper Atmosphere and Space Research Laboratory, Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Faculty of Engineering, Shinshu University"}]},"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":"1987-09-01"}],"displaytype":"detail","filename":"KJ00000767747.pdf","filesize":[{"value":"82.7 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000767747","url":"https://nipr.repo.nii.ac.jp/record/3539/files/KJ00000767747.pdf"},"version_id":"5dce6fdb-98d5-4969-9510-f6027d401347"}]},"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":"LIDAR OBSERVATIONS OF THE MESOSPHERIC SODIUM LAYER AT SYOWA STATION, ANTARCTICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"LIDAR OBSERVATIONS OF THE MESOSPHERIC SODIUM LAYER AT SYOWA STATION, ANTARCTICA"}]},"item_type_id":"1","owner":"4","path":["525"],"pubdate":{"attribute_name":"公開日","attribute_value":"1987-09-01"},"publish_date":"1987-09-01","publish_status":"0","recid":"3539","relation_version_is_last":true,"title":["LIDAR OBSERVATIONS OF THE MESOSPHERIC SODIUM LAYER AT SYOWA STATION, ANTARCTICA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:32:37.797150+00:00"}
