The authors developed direct assimilation of reflectivities (Ze) from the Dual-Frequency Precipitation Radar (DPR) on board the Global Precipitation Measurement (GPM) Core Observatory to improve mesoscale predictions. Based on comparisons with Ze observations, this cloud resolving model mostly reproduced Ze but produced overestimations of Ze induced by excessive snow with large diameter particles. With an ensemble-based variational scheme and preprocessing steps to properly treat reflectivity observations including conservative quality control and superobbing procedures, the authors assimilated DPR Ze and/or rain-affected radiances of GPM Microwave Imager (GMI) for the case of Typhoon Halong in July 2014. With the vertically resolving capability of DPR, the authors effectively selected Ze observations most suited to data assimilation, for example, by removing Ze above the melting layer to avoid contamination due to model bias. While the GMI radiance had large impacts on various control variables, the DPR made a fine delicate analysis of the rain mixing ratio and updraft. This difference arose from the observation characteristics (coverage width and spatial resolution), sensitivities represented in the observation operators, and structures of the background error covariance. Because the DPR assimilation corrected excessive increases in rain and clouds due to the radiance assimilation, the combined use of DPR and GMI generated more accurate analysis and forecast than separate use of them with respect to the agreement of observations and tropical cyclone position errors.","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: PA1610020000","subitem_description_type":"Other"}]},"item_7_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"アメリカ気象学会"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"American Meteorological Society"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.1175/MWR-D-15-0399.1"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1175/MWR-D-15-0399.1","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0027-0644","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":"AA0074822X","subitem_source_identifier_type":"NCID"}]},"item_7_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"気象庁気象研究所"},{"subitem_text_value":"気象庁気象研究所"},{"subitem_text_value":"宇宙航空研究開発機構地球観測研究センター(JAXA)(EORC): 気象庁気象研究所"},{"subitem_text_value":"リモート・センシング技術センター"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Meteorological Research Institute, Japan Meteorological Agency"},{"subitem_text_language":"en","subitem_text_value":"Meteorological Research Institute, Japan Meteorological Agency"},{"subitem_text_language":"en","subitem_text_value":"Earth Observation Research Center, Japan Aerospace Exploration Agency (JAXA)(EORC)"},{"subitem_text_language":"en","subitem_text_value":"Remote Sensing Technology Center of Japan"}]},"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":"岡本, 幸三"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"青梨, 和正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"久保田, 拓志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田島, 知子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okamoto, Kozo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aonashi, Kazumasa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kubota, Takuji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tashima, Tomoko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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":"Experimental Assimilation of the GPM Core Observatory DPR Reflectivity Profiles for Typhoon Halong","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experimental Assimilation of the GPM Core Observatory DPR Reflectivity Profiles for Typhoon Halong","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":"22650","relation_version_is_last":true,"title":["Experimental Assimilation of the GPM Core Observatory DPR Reflectivity Profiles for Typhoon Halong"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:17:37.336629+00:00"}
