Siple (76°S, 84°W) and Halley (76°S, 27°W) are both sited near L≈4.2 and use essentially identical digital HF sounding radars. Even under quiet conditions, systematic differences in N_mF_2 and h_mF_2 can be observed at the two sites. Insight into the source of these differences can be obtained from a comparison of the ionospheric data with theoretical data derived from the USU global ionospheric model. Under austral winter conditions, a relatively good model-observational comparison is obtained. However, for austral summer conditions this agreement is poorer, apparently due to the simplicity of the neutral wind incorporated into the ionospheric model.","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":"Center for Atmospheric and Space Sciences, Utah State University/Center for Atmospheric and Space Sciences, Utah State University/British Antarctic Survey"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1987-08-01"}],"displaytype":"detail","filename":"KJ00000012744.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012744","url":"https://nipr.repo.nii.ac.jp/record/2191/files/KJ00000012744.pdf"},"version_id":"12194f23-46ad-43d8-a265-accbaceef60f"}]},"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 results from a comparison of ground-based ionosphric measurements in the southern hemisphere and the USU global ionospheric model","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"First results from a comparison of ground-based ionosphric measurements in the southern hemisphere and the USU global ionospheric model","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["402"],"pubdate":{"attribute_name":"公開日","attribute_value":"1987-08-01"},"publish_date":"1987-08-01","publish_status":"0","recid":"2191","relation_version_is_last":true,"title":["First results from a comparison of ground-based ionosphric measurements in the southern hemisphere and the USU global ionospheric model"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:52:01.003492+00:00"}
