The laser transmitter was newly developed and included two injection-seeded Nd: YAG lasers. Regular observations were performed using the two-frequency technique as demonstrated by C.Y. She et al. (Geophys. Res. Lett., 17, 929, 1990), with a spatial resolution of about 1 km and a temporal resolution of 6 min. The temperature structures of the 85km to 105km region of the upper atmosphere were measured by Na D_2 Doppler profile-fitting as well as the two-frequency technique. Temperatures derived from the two techniques agreed well and were consistent with the MSIS 90 model temperature structure. Night-time temperature variations over a 15-hour period were measured in May 2000. A large temperature fluctuation with an interval of about 4 hours, and an amplitude of 60 K (probably caused by gravity waves) was observed. From the average night temperature profile, the mesopause was determined to be located at 102km, and have a temperature of 180K. These values are similar to winter values observed in the northern hemisphere.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006328","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":"AA11397422","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":"Department of Information Engineering, Shinshu University/Department of Information Engineering, Shinshu University/Department of Information Engineering, Shinshu University/National Institute of Polar Research/Department of Information Engineering, Shinshu University/Department of Information Engineering, Shinshu University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2001-09-01"}],"displaytype":"detail","filename":"KJ00000048068.pdf","filesize":[{"value":"972.5 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000048068","url":"https://nipr.repo.nii.ac.jp/record/6328/files/KJ00000048068.pdf"},"version_id":"dd05e439-dcbc-4d3b-831e-c472e5355225"}]},"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":"First mesopause temperature measurements using sodium lidar observations in the Antarctic region","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"First mesopause temperature measurements using sodium lidar observations in the Antarctic region"}]},"item_type_id":"1","owner":"4","path":["805"],"pubdate":{"attribute_name":"公開日","attribute_value":"2001-09-01"},"publish_date":"2001-09-01","publish_status":"0","recid":"6328","relation_version_is_last":true,"title":["First mesopause temperature measurements using sodium lidar observations in the Antarctic region"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:03:02.012370+00:00"}
