The main characteristic of this method is the inclusion of extremely high N_2O emission rates, ‘outlier’, which are normally excluded from estimation. High N_2O emission rates were estimated using the regression model obtained from the measured N_2O values and the amounts of N surplus; normal N_2O emission rates were estimated using the regression model obtained from the measured values and the amount of N input. The probability of occurrence of a high flux was used to incorporate calculated high and normal N_2O emissions into one. The annual N_2O emission rate from the livestock farm in the watershed (467 ha), estimated using the HEI method, was 1156 ± 147 kg N year^<−1> over a 5-year period. The annual N_2O emission rates calculated using the site-specific emission factor (EF = 0.0789) and the emission factor of the Intergovernmental Panel on Climate Change (EF = 0.01) were 1838 ± 585 kg N year^<−1> and 673 (522-1103) kg N year^<−1>, respectively. The estimated value using the measure-and-multiply method, in which each land-use area is multiplied by the representative emission rate for each land-use type, was 964 (509-1610) kg N year^<−1>. The N_2O emission rates estimated by our newly developed method were consistent with the values calculated by the measure-and-multiply method and offered improvement over this measure because the new measure can also predict future N_2O emission rates from the watershed.","subitem_description_type":"Abstract"}]},"item_2_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Blackwell Publishing"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1111/j.1747-0765.2009.00395.x","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"The definitive version is available at www.blackwellsynergy.com"}]},"item_2_rights_16":{"attribute_name":"権利（URI）","attribute_value_mlt":[{"subitem_rights":"http://dx.doi.org/10.1111/j.1747-0765.2009.00395.x | http://dx.doi.org/10.1111/j.1747-0765.2009.00395.x"}]},"item_2_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0038-0768","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KATAYANAGI, Nobuko"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"SAWAMOTO, Takuji","creatorNameLang":"en"},{"creatorName":"澤本, 卓治","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"HAYAKAWA, Atsushi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HATANO, Ryusuke"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-09-14"}],"displaytype":"detail","filename":"S-881_Sawamoto.pdf","filesize":[{"value":"630.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"S-881_Sawamoto.pdf","url":"https://rakuno.repo.nii.ac.jp/record/393/files/S-881_Sawamoto.pdf"},"version_id":"c66d2c5a-4105-42c1-ae58-86f64bf2683c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"emission factor","subitem_subject_scheme":"Other"},{"subitem_subject":"high-emission-incorporation method","subitem_subject_scheme":"Other"},{"subitem_subject":"measure-and-multiply method","subitem_subject_scheme":"Other"},{"subitem_subject":"outlier","subitem_subject_scheme":"Other"},{"subitem_subject":"uncertainty","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":"New method for the estimation of nitrous oxide emission rates from an agricultural watershed","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"New method for the estimation of nitrous oxide emission rates from an agricultural watershed"}]},"item_type_id":"2","owner":"3","path":["14"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-03-31"},"publish_date":"2011-03-31","publish_status":"0","recid":"393","relation_version_is_last":true,"title":["New method for the estimation of nitrous oxide emission rates from an agricultural watershed"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-30T01:59:14.308029+00:00"}
