We performed quality control prior to data analysis. Our analysis showed that the amount of surface melting increased in years with warm summers, when sensible heat transport and net shortwave radiation increased. Positive feedback between snow grain growth and near-infrared albedo reduction played an important role in the melting process. The relationship between the North Atlantic Oscillation index and surface melt flux revealed that July 2012 was an extraordinary year, characterised by a significant increase in melting caused partly by increased downward longwave radiation from the lower clouds, which suppressed net longwave cooling, and partly by the increases in sensible heat and net shortwave radiation that are generally associated with warm summers.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "公益社団法人 日本雪氷学会", "subitem_publisher_language": "ja"}, {"subitem_publisher": "The Japanese Society of Snow and Ice", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.5331/seppyo.83.2_143"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1883-6267", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "廣瀨 聡", "creatorNameLang": "ja"}, {"creatorName": "HIROSE Satoshi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "青木 輝夫", "creatorNameLang": "ja"}, {"creatorName": "AOKI Teruo", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "庭野 匡思", "creatorNameLang": "ja"}, {"creatorName": "NIWANO Masashi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "的場 澄人", "creatorNameLang": "ja"}, {"creatorName": "MATOBA Sumito", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "谷川 朋範", "creatorNameLang": "ja"}, {"creatorName": "TANIKAWA Tomonori", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "山口 悟", "creatorNameLang": "ja"}, {"creatorName": "YAMAGUCHI Satoru", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "山崎 哲秀", "creatorNameLang": "ja"}, {"creatorName": "YAMASAKI Tetsuhide", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_title": "北西グリーンランド氷床上SIGMA-Aサイトで 観測された雪面熱収支の特徴", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "北西グリーンランド氷床上SIGMA-Aサイトで 観測された雪面熱収支の特徴", "subitem_title_language": "ja"}, {"subitem_title": "Surface energy balance observed at the SIGMA-A site on the northwest Greenland ice sheet", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5933", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5933", "relation": {}, "relation_version_is_last": true, "title": ["北西グリーンランド氷床上SIGMA-Aサイトで 観測された雪面熱収支の特徴"], "weko_shared_id": -1}
