Recently, numerical simulation models become essential to planning of missions, analyzing and providing observational data. On the other hand, the simulation models used in these researches have become so expanded and complicated that it is difficult for one researcher to understand, develop, maintain and provide their source codes. “Model gap problem” is one of the difficulties with numerical simulation models. In order to check the validity of the simulation models and to develop them further, it is necessary to perform numerical calculations with numerical models with various complexities and to compare the numerical results mutually. Expansion of the simulation models makes difficult to perform such inter-comparison for checking of the validity. In an attempt to overcome the“ model gap problem”, we have been proceeding “dcmodel project”, where a series of hierarchical numerical models with various complexity is developed and maintained as a voluntary activity. The numerical models are developed with the following intentions: 1) Hierarchical models with various complexities. 2) Common “style” of programming in order to ensure readability. 3) Open source codes to the public. 4) Scalability of the models in order to ensure execution on various platforms. 5) Stressing the importance of documentation and presenting a method for producing reference manuals. The series of hierarchical models enable us to conduct multiple numerical experiments with multiple models easily, which will lead to a deeper understanding of various phenomena in planetary atmospheres.","subitem_description_type":"Other"}]},"item_3_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_3_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_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0062302016","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-RR-13-010","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1113","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1192675X","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"京都大学数理解析研究所"},{"subitem_text_value":"神戸大学地球惑星科学専攻 : 神戸大学惑星科学研究センター"},{"subitem_text_value":"理化学研究所計算科学研究機構"},{"subitem_text_value":"神戸大学地球惑星科学専攻 : 神戸大学惑星科学研究センター"},{"subitem_text_value":"-"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Research Institute for Mathematical Sciences, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Department of Earth and Planetary Sciences, Kobe University : Center for Planetary Science, Kobe University"},{"subitem_text_language":"en","subitem_text_value":"RIKEN Advanced Institute for Computational Science"},{"subitem_text_language":"en","subitem_text_value":"Department of Earth and Planetary Sciences, Kobe University : Center for Planetary Science, Kobe University"},{"subitem_text_language":"en","subitem_text_value":"-"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"竹広, 真一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高橋, 芳幸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"西澤, 誠也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"林, 祥介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"地球流体電脳倶楽部"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takehiro, Shinichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takahashi, Yoshiyuki O.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishizawa, Seiya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hayashi, Yoshiyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"GFD-Dennou Club","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"62302016.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"62302016.pdf","url":"https://jaxa.repo.nii.ac.jp/record/1966/files/62302016.pdf"},"version_id":"6da7e8b5-64a1-465d-99d4-dbe08036f431"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"数値モデルを用いた惑星大気研究と地球流体電脳倶楽部DCMODELプロジェクト","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"数値モデルを用いた惑星大気研究と地球流体電脳倶楽部DCMODELプロジェクト"}]},"item_type_id":"3","owner":"1","path":["77","1405","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"1966","relation_version_is_last":true,"title":["数値モデルを用いた惑星大気研究と地球流体電脳倶楽部DCMODELプロジェクト"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T20:21:56.778604+00:00"}
