However a long-term variation of TSI was not detected. The solar irradiance at the earth's surface is considerably smaller (170 W^<-2>) than previously believed (e.g. 198 W m^<-2> of IPCC AR4). The previous overestimation is due to the underestimation of the absorption of solar radiation in the atmosphere. The absorption of solar radiation in the atmosphere at about 90 W m^<-2>, or 25-28% of the primary solar radiation from space. The global mean atmospheric downward terrestrial radiation is much larger (345 W m^<-2>) than previously assumed (325 W m^<-2> of IPCC AR4). The Arctic has regions of negative annual net radiation, a very rare phenomenon on the globe. These regions are the Central Arctic Ocean with its multi-year ice coverage and the accumulation area of the Greenland ice sheet. The energy balance of these regions is presented. Long-wave incoming radiation has been increasing in the Arctic at a rate of 4-5 W m^<-2>/Decade. The Greenland ice sheet exhibits a large vertical difference in net radiation from the ablation area to the dry snow zone in summer. It ranges from 80 W m^<-2> in the ablation area to 20 W m^<-2> at the equilibrium line and to 10 W m^<-2> in the dry snow zone. This gradient determines the melt gradient on the ice sheet, and is mainly caused by the altitude variation in atmospheric long-wave radiation, seconded by the albedo variation. The effect of albedo in summer for various surfaces is discussed. Simulation capabilities of radiation for many GCMs are investigated.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"　熱収支気候学はこの数年間に大きな進歩を経験したので、全球の新しい熱収支を、次に北極について更新されつつある熱収支を述べる。まず太陽常数は、すこし小さい1361 Wm?２を用いる。地表での全天日射は従来の値よりはるかに小さい170 Wm?２となり、大気の吸収率が遥かに大きく25から28％と推定された。大気から地表面への長波は従来の値より大幅に増加し全球平均で345 Wm?２前後となった。北極では、多年氷に覆われている北極海中央部とグリーンランド氷床の涵養域で、年平均で正味放射が負になっている。北極域の地表面への長波放射の値は、最近20年間の平均で4から5 Wm?２／10年の率で増加している。グリーンランド氷床の放射平衡は、正確に知られるようになり、北極の諸表面の主なアルベドも最新の情報を提出する。（348）","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110009418535","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2012.03.003"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2012.03.003","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"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":"Ohmura, Atsumu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ohmura, Atsumu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Energy balance","subitem_subject_scheme":"Other"},{"subitem_subject":"Radiation","subitem_subject_scheme":"Other"},{"subitem_subject":"Arctic","subitem_subject_scheme":"Other"},{"subitem_subject":"Greenland","subitem_subject_scheme":"Other"},{"subitem_subject":"GCM","subitem_subject_scheme":"Other"},{"subitem_subject":"Energy balance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Radiation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Arctic","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Greenland","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"GCM","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":"Present status and variations in the Arctic energy balance","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Present status and variations in the Arctic energy balance"},{"subitem_title":"Present status and variations in the Arctic energy balance","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"27","path":["1347"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-16"},"publish_date":"2014-10-16","publish_status":"0","recid":"10157","relation_version_is_last":true,"title":["Present status and variations in the Arctic energy balance"],"weko_creator_id":"27","weko_shared_id":27},"updated":"2023-07-25T16:21:22.425620+00:00"}
