Tables were constructed at three spectral resolutions (2, 5, and 10 cm−1) with quadrature values (point and weight) and numbers optimized using simulated sky radiances at ground level, which had accuracies of ≤ 0.5% for sub-bands of 10cm−1. Although high-resolution WV-CKD requires numerous quadrature points, the number of executions of the radiative transfer model is reduced to approximately 1/46 of the number used in the line-by-line approach by our WV-CKD with a resolution of 2 cm−1. Furthermore, we confirmed through several simulations that WV-CKD could be used to compute radiances with various vertical profiles. The accuracy of convolved direct solar irradiance and diffuse radiance at a full width at half maximum (FWHM) of 10 nm, computed with the WV-CKD, is < 0.3%. In contrast, the accuracy of convolved normalized radiance, which is the ratio of diffuse radiance to direct solar irradiance, at an FWHM of 10 nm computed with the WV-CKD is < 0.11%. This accuracy is lower than the observational uncertainty of a ground-based angular-scanning radiometer (approximately 0.5%). Finally, we applied the SKYMAP and DSRAD algorithms (Momoi et al. in Atmos Meas Tech 13:2635–2658, 2020. https://doi.org/10.5194/amt-13-2635-2020) to SKYNET observations (Chiba, Japan) and compared the results with microwave radiometer values. The precipitable water vapor (PWV) derived with the WV-CKD showed better agreement (correlation coefficient γ = 0.995, slope = 1.002) with observations than PWV derived with the previous CKD table (correlation coefficient γ = 0.984, slope = 0.926) by Momoi et al. (Momoi et al., Atmos Meas Tech 13:2635–2658, 2020). Through application of the WV-CKD to actual data analysis, we found that an accurate CKD table is essential for estimating PWV from sky-radiometer observations."}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Nature"}]},"item_3_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1186/s40645-022-00467-6","subitem_relation_type_select":"DOI"}}]},"item_3_relation_13":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher's Version/PDF (OpenAccess)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1186/s40645-022-00467-6","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"Springer Nature"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.springernature.com/jp","subitem_relation_type_select":"URI"}}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Momoi, Masahiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Irie, Hitoshi"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI"}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"関口, 美保","creatorNameLang":"ja"},{"creatorName":"セキグチ, ミホ","creatorNameLang":"ja-Kana"},{"creatorName":"Sekiguchi, Miho","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyNameLang":"ja"},{"familyNameLang":"ja-Kana"},{"familyNameLang":"ja-Kana"}],"givenNames":[{"givenNameLang":"ja"},{"givenNameLang":"ja-Kana"},{"givenNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Nakajima, Teruyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takenaka, Hideaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miura, Kazuhiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aoki, Kazuma"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Atmospheric gas absorption","subitem_subject_scheme":"Other"},{"subitem_subject":"Correlated k-distribution","subitem_subject_scheme":"Other"},{"subitem_subject":"Radiative transfer","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"}]},"item_title":"Rapid, accurate computation of narrow-band sky radiance in the 940 nm gas absorption region using the correlated k-distribution method for sun-photometer observations","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Rapid, accurate computation of narrow-band sky radiance in the 940 nm gas absorption region using the correlated k-distribution method for sun-photometer observations"}]},"item_type_id":"3","owner":"15","path":["363","636"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-05-17"},"publish_date":"2022-05-17","publish_status":"0","recid":"2452","relation_version_is_last":true,"title":["Rapid, accurate computation of narrow-band sky radiance in the 940 nm gas absorption region using the correlated k-distribution method for sun-photometer observations"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-04-23T05:03:05.908678+00:00"}
