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","filename":"KJ00004163414.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","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"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-03-01"},"publish_date":"2006-03-01","publish_status":"0","recid":"2516","relation_version_is_last":true,"title":["Micrometeorological measurements of methane flux at a boreal forest in central Alaska"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:59:20.986574+00:00"}
