The procedure is composed of two parts as: 1. Aerosol retrieval from satellite reflectance measurements. 2. Conversion into PM2.5 concentration from retrieved aerosol optical thickness (AOT). The comparison of retrieved AOT from GOSAT/CAI with NASA/AERONET AOT measurements is performed in Osaka region. As results, a root mean square error value of AOT (RMSE-AOT) is around 0.09 in all retrieved wavelengths and the RMSE-AOT at a wavelength of 670 nm over Osaka region is around 0.07. Finally, satellite retrieved PM2.5 concentration also coincides with in situ PM2.5 measurements, RMSE-PM2.5 is around 6 ug/m3.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C);  研究期間：2013～2015;   課題番号：25340019;   研究分野：環境動態解析;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-25340019/"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"連携研究者"},{"subitem_text_value":"連携研究者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"SANO, Itaru"},{"subitem_text_language":"en","subitem_text_value":"MUKAI, Sonoyo"},{"subitem_text_language":"en","subitem_text_value":"NAKATA, Makiko"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 教授"},{"subitem_text_value":"京都情報大学院大学; 教授"},{"subitem_text_value":"近畿大学総合社会学部; 准教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐野, 到"},{"creatorName":"サノ, イタル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"向井, 苑生"},{"creatorName":"ムカイ, ソノヨ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"中田, 真木子"},{"creatorName":"ナカタ, マキコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-17"}],"displaytype":"detail","filename":"25340019seika.pdf","filesize":[{"value":"150.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"25340019seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/18054/files/25340019seika.pdf"},"version_id":"1168475a-eacb-4fe0-a75e-913ffe30f0f3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"PM2.5","subitem_subject_scheme":"Other"},{"subitem_subject":"Aerosol","subitem_subject_scheme":"Other"},{"subitem_subject":"DRAGON","subitem_subject_scheme":"Other"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"衛星を用いた都市域におけるPM2.5濃度の広域分布推定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"衛星を用いた都市域におけるPM2.5濃度の広域分布推定"},{"subitem_title":"Estimation of PM2.5 distribution over mega city based on satellite measurements","subitem_title_language":"en"}]},"item_type_id":"8","owner":"29","path":["4296"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-17"},"publish_date":"2016-10-17","publish_status":"0","recid":"18054","relation_version_is_last":true,"title":["衛星を用いた都市域におけるPM2.5濃度の広域分布推定"],"weko_creator_id":"29","weko_shared_id":-1},"updated":"2023-06-20T22:09:36.397674+00:00"}
