The treatment of the radiative transfer problem concerning the optical quantities is mainly based on the IMS (improved multiple and single scattering) method, which uses the delta-M approximation for the truncation of the aerosol phase function and corrects the solution for the first- and second-order scattering. Both linear and nonlinear inversion methods can be used for retrieving the size distribution. Improved calibration methods for both direct and diffuse radiation, the data-analysis procedure, the results from the proposed code, and several connected problems are discussed. The results can be summarized as follows: (a) the SKYRAD. pack code can retrieve the columnar aerosol features with accuracy and efficiency in several environmental situations, provided the input parameters are correctly given; (b) when data of both direct and diffuse solar radiation are used, the detectable radius interval for aerosol particles is approximately from 0.03 to 10\u03bcm; (c) besides the retrieval of the aerosol features, the data-analysis procedure also permits the determination of average values for three input parameters (real and imaginary aerosol refractive index, ground albedo) from the optical data; (d) absolute calibrations for the sky radiometer are not needed, and calibrations for direct and diffuse radiation can be carried out with field data; (e) the nonlinear inversion gives satisfactory results in a larger radius interval, without the unrealistic humps that occur with the linear inversion, but the results strongly depend on the first-guess spectrum; (f) aerosol features retrieved from simulated data showed a better agreement with the given data for the linear inversion than for the nonlinear inversion.","subitem_description_type":"Abstract"}]},"item_2_publisher_20":{"attribute_name":"\u51fa\u7248\u8005","attribute_value_mlt":[{"subitem_publisher":"Optical Society of America"}]},"item_2_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1364/AO.35.002672","subitem_relation_type_select":"DOI"}}]},"item_2_relation_26":{"attribute_name":"\u7570\u7248\u3067\u3042\u308b","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.opticsinfobase.org/ao/abstract.cfm?uri=ao-35-15-2672","subitem_relation_type_select":"URI"}}]},"item_2_rights_12":{"attribute_name":"\u6a29\u5229","attribute_value_mlt":[{"subitem_rights":"\u00a9 1996 Optical Society of America"}]},"item_2_source_id_10":{"attribute_name":"\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00543409","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00036935","subitem_source_identifier_type":"ISSN"}]},"item_2_subject_15":{"attribute_name":"\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5","attribute_value_mlt":[{"subitem_subject":"451","subitem_subject_scheme":"NDC"}]},"item_2_text_4":{"attribute_name":"\u8457\u8005\u6240\u5c5e","attribute_value_mlt":[{"subitem_text_value":"Center for Climate System Research, University of Tokyo"},{"subitem_text_value":"Institute for Atmospheric Physics, Consiglio Nazionale delle Richerche"},{"subitem_text_value":"Consiglio Nazionale delle Richerche, Cagliari Research Area"},{"subitem_text_value":"Department of Physics, University of Cagliari"},{"subitem_text_value":"NASA Goddard Space Flight Center"}]},"item_creator":{"attribute_name":"\u8457\u8005","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakajima, Teruyuki"}],"nameIdentifiers":[{"nameIdentifier":"3248","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tonna, Glauco"}],"nameIdentifiers":[{"nameIdentifier":"3249","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Rao, Ruizhong"}],"nameIdentifiers":[{"nameIdentifier":"3250","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Boi, Paolo"}],"nameIdentifiers":[{"nameIdentifier":"3251","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kaufman, Yoram"}],"nameIdentifiers":[{"nameIdentifier":"3252","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Holben, Brent"}],"nameIdentifiers":[{"nameIdentifier":"3253","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"\u30d5\u30a1\u30a4\u30eb\u60c5\u5831","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-30"}],"displaytype":"detail","filename":"Nakajima1996OSA_H24P35.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Nakajima1996OSA_H24P35.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/845/files/Nakajima1996OSA_H24P35.pdf"},"version_id":"2b344526-b91a-4f6d-a238-d8961fe0d216"}]},"item_language":{"attribute_name":"\u8a00\u8a9e","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"\u8cc7\u6e90\u30bf\u30a4\u30d7","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Use of sky brightness measurements from ground for remote sensing of particulate polydispersions","item_titles":{"attribute_name":"\u30bf\u30a4\u30c8\u30eb","attribute_value_mlt":[{"subitem_title":"Use of sky brightness measurements from ground for remote sensing of particulate polydispersions"}]},"item_type_id":"2","owner":"1","path":["9/10/11","40/117/118"],"pubdate":{"attribute_name":"\u516c\u958b\u65e5","attribute_value":"2017-01-06"},"publish_date":"2017-01-06","publish_status":"0","recid":"845","relation_version_is_last":true,"title":["Use of sky brightness measurements from ground for remote sensing of particulate polydispersions"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2021-03-02T08:42:35.410687+00:00"}
