The AMSR2 provides multifrequency measurements of microwave energy (brightness temperature) emitted by the Earth's surface and atmosphere. However, each frequency field of view (FOV) differs in size because of its hardware design. For the retrieval of more accurate geophysical parameters from multifrequency brightness temperatures, the brightness temperatures should be modified to be the same as measured in the same FOV. The Backus-Gilbert (BG) method is one of the antenna pattern matching techniques used for this modification. We applied the BG method to the AMSR2 data to define a new data set of modified brightness temperatures, a level 1R (L1R) product that is freely and widely available. We optimized the implementation of the BG method to obtain the L1R product, with smoothing factors dynamically determined for all modified brightness temperatures. This paper describes the implementation method, including the criterion used to determine the smoothing factors and presents a quality assessment of the L1R product.","subitem_description_type":"Other"}]},"item_7_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_7_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1610002000","subitem_description_type":"Other"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Electrical and Electronics Engineers (IEEE)"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.1109/TGRS.2015.2465170"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1109/TGRS.2015.2465170","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0196-2892","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00231483","subitem_source_identifier_type":"NCID"}]},"item_7_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構第一宇宙技術部門地球観測研究センター(JAXA)(EORC)"},{"subitem_text_value":"三菱スペース・ソフトウェア株式会社"},{"subitem_text_value":"宇宙航空研究開発機構第一宇宙技術部門地球観測研究センター(JAXA)(EORC)"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Earth Observation Research Center, Space Technology Directorate I, Japan Aerospace Exploration Agency (JAXA)(EORC)"},{"subitem_text_language":"en","subitem_text_value":"Mitsubishi Space Software Co., Ltd."},{"subitem_text_language":"en","subitem_text_value":"Earth Observation Research Center, Space Technology Directorate I, Japan Aerospace Exploration Agency (JAXA)(EORC)"}]},"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":"前田, 崇"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"谷口, 悠司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"今岡, 啓治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Maeda, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Taniguchi, Yuji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Imaoka, Keiji","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Advanced Microwave Scanning Radiometer-2 (AMSR2)","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Backus-Gilbert (BG) method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"convolution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"field of view (FOV)","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"microwave radiometer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"water cycle monitoring","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":"GCOM-W1 AMSR2 Level 1R Product: Dataset of Brightness Temperature Modified Using the Antenna Pattern Matching Technique","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"GCOM-W1 AMSR2 Level 1R Product: Dataset of Brightness Temperature Modified Using the Antenna Pattern Matching Technique","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-06-13"},"publish_date":"2016-06-13","publish_status":"0","recid":"22633","relation_version_is_last":true,"title":["GCOM-W1 AMSR2 Level 1R Product: Dataset of Brightness Temperature Modified Using the Antenna Pattern Matching Technique"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T19:59:09.410005+00:00"}
