One method uses only one channel data to interpolate the ice concentration between 0 and 100% corresponding to the open water and the snow cover, respectively. This method yieds an uncertainty owing to the variation of albedo by the surface condition change. Another method uses two-channel data to derive not only the ice concentration but also the ice surface condition and can eliminate uncertainties involved in the first method. The ice surface condition is expressed by \"snow coverage\". Air photographs are compared with the satellite data. They are helpful to discuss the surface condition of sea ice. Time variations of the concentration and surface condition of summer sea ice are discussed.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008507","subitem_identifier_reg_type":"JaLC"}]},"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_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"551.46","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"University of Electro-Communications"},{"subitem_text_language":"en","subitem_text_value":"University of Electro-Communications"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"電気通信大学"},{"subitem_text_value":"電気通信大学"},{"subitem_text_value":"国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1986-07-01"}],"displaytype":"detail","filename":"KJ00000139721.pdf","filesize":[{"value":"554.7 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000139721","url":"https://nipr.repo.nii.ac.jp/record/8507/files/KJ00000139721.pdf"},"version_id":"1efa0da1-dad7-48fc-8d2d-438a66a740b0"}]},"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":"AVHRR可視・近赤外画像による海氷密集度の算出","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"AVHRR可視・近赤外画像による海氷密集度の算出"},{"subitem_title":"Determination of sea ice concentration from AVHRR visible and near infrared imagery","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1084"],"pubdate":{"attribute_name":"公開日","attribute_value":"1986-07-01"},"publish_date":"1986-07-01","publish_status":"0","recid":"8507","relation_version_is_last":true,"title":["AVHRR可視・近赤外画像による海氷密集度の算出"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:01:55.747478+00:00"}
