The commonly used multiplication transmittance scheme is not acceptable when correlation existing in the practical absorption spectra becomes strong. Therefore an optimized scheme to obtain k distribution parameters for overlapping bands is developed in this paper based on the completely uncorrelated, perfectly correlated, and partly correlated schemes. Two partial correlation formulae are given in the paper. Calculations of radiative flux and atmospheric heating (or cooling) rate are validated in detail using a line-by-line model described in the paper for six model atmospheres. The optimized scheme developed here has an accuracy in longwave clear skies of 0.07 Kd(-1) in the entire troposphere and 0.35 Kd(-1) above the tropopause; the accuracy of upward, downward, and net fluxes is 0.76 Wm(-2) at all altitudes. In shortwave region, the absolute errors of the heating rate are less than 0.05 Kd(-1) in the troposphere and less than 0.25 Kd(-1) above the tropopause; net flux errors are less than 0.9 Wm(-2) at all altitudes. For an ensemble of 42 diverse atmospheres, the new scheme guarantees an average maximum error of longwave heating rate of 0.068 Kd(-1) in troposphere, 0.22 Kd(-1) above tropopause, and an accuracy of 1.1 Wm(-2) of radiative net flux for all the levels. For a case of doubled CO2 concentration, radiative forcing calculations have an accuracy of 0.04 Wm(-2).","subitem_description_type":"Abstract"}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Geophysical Union"}]},"item_2_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1029/2002JD003358","subitem_relation_type_select":"DOI"}}]},"item_2_relation_26":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doir.org/10.1029/2002JD003358","subitem_relation_type_select":"URI"}}]},"item_2_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright 2003 by the American Geophysical Union."}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10819765","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"01480227","subitem_source_identifier_type":"ISSN"}]},"item_2_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"451","subitem_subject_scheme":"NDC"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Integrated Modeling Research Program, Frontier Research System for Global Change"},{"subitem_text_value":"Center for Climate System Research, University of Tokyo"},{"subitem_text_value":"State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of Atmospheric Physics"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Zhang, Hua"}],"nameIdentifiers":[{"nameIdentifier":"3452","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakajima, Teruyuki"}],"nameIdentifiers":[{"nameIdentifier":"3453","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shi, Guangyu"}],"nameIdentifiers":[{"nameIdentifier":"3454","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Tsuneaki"}],"nameIdentifiers":[{"nameIdentifier":"3455","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Imasu, Ryoichi"}],"nameIdentifiers":[{"nameIdentifier":"3456","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-30"}],"displaytype":"detail","filename":"Nakajima2003JGRA_H24P85.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Nakajima2003JGRA_H24P85.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/886/files/Nakajima2003JGRA_H24P85.pdf"},"version_id":"d2c6c9d0-ae41-405d-86ab-1c432fc87356"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"atmospheric absorption","subitem_subject_scheme":"Other"},{"subitem_subject":"correlated k distribution","subitem_subject_scheme":"Other"},{"subitem_subject":"overlapping band","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":"An optimal approach to overlapping bands with correlated k distribution method and its application to radiative calculations","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"An optimal approach to overlapping bands with correlated k distribution method and its application to radiative calculations"}]},"item_type_id":"2","owner":"1","path":["11","118"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-01-10"},"publish_date":"2017-01-10","publish_status":"0","recid":"886","relation_version_is_last":true,"title":["An optimal approach to overlapping bands with correlated k distribution method and its application to radiative calculations"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:42:07.166948+00:00"}
