The results give the following. (1) The vertical electric field and current at the altitude of 30km are 0.12-0.21 V/m and 1.3-2.2 x10^\u003c-12\u003e A/m^2 respectively, and their diurnal variations are roughly consistent with the expected variation from the average world-wide thunderstorm activity. (2) The electrical conductivities were estimated from the ratio of the electric current to the electric field giving the average value of 1 x 10^\u003c-11\u003e mho/m at the altitude of 30 km. This value is about twice as large as that in Japan. This can be explained by the latitudinal effect of the cosmic ray ionization in the atmosphere. (3) Enhancements of the electric field and current were observed in both vertical and horizontal components of the magnitude of about 80 mV/m and 0.8 x 10^\u003c-12\u003e A/m^2 respectively at an initial stage of a magnetic substorm. The vertical electric field on the ground was also correspondingly enhanced by about 80 V/m at the same time. (4) Comparisons of observed horizontal electric field vectors with the magnetic fields observed at Syowa Station show that the magnetic field variations are caused by the ionospheric Hall current. (5) One hour averages of the horizontal electric field show large scale convection fields consistent with S^p_q in the polar ionosphere and with DP-2 in the equatorial magnetosphere. The average ionospheric and magnetospheric equatorial electric fields were 40 mV/m and 0.98 mV/m respectively, and corresponding plasma convection velocities were estimated to be 700 m/s and 22 km/s respectively.", "subitem_description_type": "Other"}]}, "item_1_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15094/00007830", "subitem_identifier_reg_type": "JaLC"}]}, "item_1_publisher_22": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "国立極地研究所"}]}, "item_1_source_id_13": {"attribute_name": "雑誌書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00181831", "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": "Volcanological Laboratory, Kyoto University"}, {"subitem_text_language": "en", "subitem_text_value": "Geophycial Institute, Kyoto University"}, {"subitem_text_language": "en", "subitem_text_value": "Institute of Physical and Chemical Research"}]}, "item_1_text_2": {"attribute_name": "記事種別(日)", "attribute_value_mlt": [{"subitem_text_value": "研究論文"}]}, "item_1_text_3": {"attribute_name": "記事種別(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Scientific Paper"}]}, "item_1_text_9": {"attribute_name": "著者所属(日)", "attribute_value_mlt": [{"subitem_text_value": "京都大学理学部付属火山研究施設"}, {"subitem_text_value": "京都大学理学部地球物理学教室"}, {"subitem_text_value": "理化学研究所"}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "1975-12-01"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00002476933.pdf", "filesize": [{"value": "6.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_6", "mimetype": "application/pdf", "size": 6500000.0, "url": {"label": "KJ00002476933", "url": "https://nipr.repo.nii.ac.jp/record/7830/files/KJ00002476933.pdf"}, "version_id": "dc89bec5-f9e5-402c-a476-c9ab5160a3a9"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "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": "昭和基地における成層圏電場・電流の観測", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "昭和基地における成層圏電場・電流の観測"}, {"subitem_title": "Startospheric Electric Fields and Currents Measured at Syowa Station, Antarctica", "subitem_title_language": "en"}]}, "item_type_id": "1", "owner": "4", "path": ["960"], "permalink_uri": "https://doi.org/10.15094/00007830", "pubdate": {"attribute_name": "公開日", "attribute_value": "1975-12-01"}, "publish_date": "1975-12-01", "publish_status": "0", "recid": "7830", "relation": {}, "relation_version_is_last": true, "title": ["昭和基地における成層圏電場・電流の観測"], "weko_shared_id": 4}
