An SFE is the extra ionization produced by the X-ray emission from a solar flare. We analyzed 10 intense SFE events from 1996 to 1998 using SuperDARN HF radar network and other instruments located in the northern hemisphere. Two typical ionospheric signatures associated with the solar flares are revealed, one is a sudden fade-out of backscatter echoes, and the other is an appearance or variation of field-aligned irregularities. Sudden fade-out is observed only in the sunlit hemisphere, and the appearance or variation of irregularities are observed only near the terminator. In addition, we investigated one event out of ten in detail and found that there exists a discontinuity of the electric field or conductivity around the irregularity. This fact suggests that the variation of conductivity or electric field in the E region could affect the irregularity formation in the F region.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006304","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 Geophysics, Graduate School of Science, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Data Analysis Center for Geomagnetism Kyoto, Graduate School of Science, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Reserch"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Reserch"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2000-08-01"}],"displaytype":"detail","filename":"KJ00000048044.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000048044","url":"https://nipr.repo.nii.ac.jp/record/6304/files/KJ00000048044.pdf"},"version_id":"481a51ec-fce2-43e0-99c1-1ca1dfeb5469"}]},"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":"Characteristics of solar flare effect in the high-latitude ionosphere as observed by the SuperDARN radars","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Characteristics of solar flare effect in the high-latitude ionosphere as observed by the SuperDARN radars"}]},"item_type_id":"1","owner":"4","path":["804"],"pubdate":{"attribute_name":"公開日","attribute_value":"2000-08-01"},"publish_date":"2000-08-01","publish_status":"0","recid":"6304","relation_version_is_last":true,"title":["Characteristics of solar flare effect in the high-latitude ionosphere as observed by the SuperDARN radars"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:03:21.426358+00:00"}
