One type used the eddy diffusivity obtained by CO_2 flux and CO_2 gradient. Others established the flux gradient relationship assuming Monin-Obukhov similarity. The wind speed and temperature profile functions were corrected for the influence of the roughness sublayer, and then applied to the modified gradient methods. More than 70% of the data were rejected by the strict quality control and a continental climate, such as calm wind. Although the diurnal variations of CH_4 flux by the three methods were different, the seasonal variation showed similar tendency; a weak emission on snowpack, an obvious emission around spring thaw, and CH_4 uptake in the late growing season. As calculated CH_4 flux was in the same range as with previous studies conducted by the chamber measurement.", "subitem_description_type": "Other"}]}, "item_1_source_id_13": {"attribute_name": "雑誌書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00733561", "subitem_source_identifier_type": "NCID"}]}, "item_1_text_10": {"attribute_name": "著者所属(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "International Arctic Research Center, University of Alaska/International Arctic Research Center, University of Alaska/Institution of Geosciences, University of Tsukuba/Graduate School of Natural Science and Technology, Okayama University/Graduate School of Natural Science and Technology, Okayama University/National Institute of Agro-Environmental Sciences"}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2006-03-01"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00004163414.pdf", "filesize": [{"value": "1.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_6", "mimetype": "application/pdf", "size": 1300000.0, "url": {"label": "KJ00004163414", "url": "https://nipr.repo.nii.ac.jp/record/2516/files/KJ00004163414.pdf"}, "version_id": "aa81c885-d60b-4ef1-8a52-174a2c232381"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "boreal forest, methane flux, micrometeorological technique, central Alaska", "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Micrometeorological measurements of methane flux at a boreal forest in central Alaska", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Micrometeorological measurements of methane flux at a boreal forest in central Alaska", "subitem_title_language": "en"}]}, "item_type_id": "1", "owner": "4", "path": ["413"], "permalink_uri": "https://nipr.repo.nii.ac.jp/records/2516", "pubdate": {"attribute_name": "公開日", "attribute_value": "2006-03-01"}, "publish_date": "2006-03-01", "publish_status": "0", "recid": "2516", "relation": {}, "relation_version_is_last": true, "title": ["Micrometeorological measurements of methane flux at a boreal forest in central Alaska"], "weko_shared_id": 4}
