This project, one of the ground-based study programs in Antarctica for the Middle Atmosphere Program (MAP, 1982-1985), aims at clarifying how the middle atmosphere in the 80-110km altitude region behaves in response to the energy flow from the magnetosphere into the polar ionosphere, especially during a substorm. The radar has three operation modes; spectrum mode, double-pulse mode and meteor mode. The spectrum mode provides doppler spectra of back-scattered signals from which characteristics of the plasma turbulence due to auroral activity can be investigated. Mean drift velocities of the irregularities are derived from the double-pulse mode. The drift velocity obtained by this mode ultimately can be related to the ionospheric electric field. In the meteor mode, wind motions in the 80-110km altitudes are investigated by using meteor trails.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","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":"Radio Research Laboratories/Hiraiso Branch, Radio Research Laboratories/Radio Research Laboratories/National Institute of Polar Research/National Institute of Polar Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1982-09-01"}],"displaytype":"detail","filename":"KJ00000011913.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000011913","url":"https://nipr.repo.nii.ac.jp/record/1278/files/KJ00000011913.pdf"},"version_id":"eeae6832-5e0a-4d6f-9548-c3874be3d76a"}]},"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":"A new VHF doppler radar experiment at Syowa Station, Antarctic","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A new VHF doppler radar experiment at Syowa Station, Antarctic","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["376"],"pubdate":{"attribute_name":"公開日","attribute_value":"1982-09-01"},"publish_date":"1982-09-01","publish_status":"0","recid":"1278","relation_version_is_last":true,"title":["A new VHF doppler radar experiment at Syowa Station, Antarctic"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:59:39.167955+00:00"}
