For SuperDARN Syowa East (SYE) and Kerguelen (KER) radars that intersect with ZHS, a data set comprised of adjacent range gates from nearest radar beams is used. Digisonde ion drift measurements were projected onto the direction of co-located and concurrent line-of-sight SuperDARN velocities. A comparison of the velocities shows a clear correlation (R = 0.92) between the two data sets. Projected Digisonde velocity was found to be, on average, larger than the line-of-sight SuperDARN radar velocities by a factor of 1.7. Time dependence distributions of Digisonde-SuperDARN SYE radars showed that the larger velocity discrepancies are more located at the dawnside convection cell. Considering the known features of the high-latitude convection patterns at cusp latitude, the statistical results imply the velocity discrepancies are related to the differences in the temporal and spatial evolution of plasma structures.","subitem_description_type":"Abstract"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2022.100789"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.polar.2022.100789","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Chen, Xiangcai","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Liu, Jianjun","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Liu, Ruiyuan","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hu, Hongqiao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Zhang, Beichen","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yukimatu, Akira Sessai","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Doppler shift","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Plasma flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"SuperDARN HF radar","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Digisonde portable sounder DPS","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Polar ionosphere","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Comparison of Digisonde derived ion drifts and SuperDARN line-of-sight velocities over Zhongshan Station, Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Comparison of Digisonde derived ion drifts and SuperDARN line-of-sight velocities over Zhongshan Station, Antarctica"},{"subitem_title":"Comparison of Digisonde derived ion drifts and SuperDARN line-of-sight velocities over Zhongshan Station, Antarctica","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"26","path":["2087"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-05-26"},"publish_date":"2022-05-26","publish_status":"0","recid":"16910","relation_version_is_last":true,"title":["Comparison of Digisonde derived ion drifts and SuperDARN line-of-sight velocities over Zhongshan Station, Antarctica"],"weko_creator_id":"26","weko_shared_id":-1},"updated":"2023-07-25T12:48:42.412210+00:00"}
