Spectral measurements were conducted under the solar zenith angle of approximately the Brewster angle in order to quantify the polarization properties of light reflected from snow. We obtained spectral DLPs for five different snow types in both field campaigns including precipitation particles, needles, surface hoar, melt forms, and melt freeze crust covering the snow surface. The measurements showed that in the visible region the spectral dependence of the DLP was small while in the near infrared region it increased with increasing snow grain size with some distinct local peaks. The angular dependence indicated that the DLP exhibited small angular dependence in the visible region while in the near‐infrared region it exhibited large and broad peaks in the forward direction. Especially for the melt‐freeze crust, the DLP approached 1.0 at wavelengths close to λ = 1.5 and 2.0 μm. These features can be explained by (1) the relative contribution of surface versus volume scattering to the reflected light, (2) the incident angle (solar zenith angle) of approximately the Brewster angle, and (3) the ratio between direct and diffuse components of the solar radiation incident on the snow surface. The spectral DLP was found to be quiet sensitive to the incident solar radiation and solar elevation as well as snow optical properties. Comparison between the spectral DLP and snow grain size obtained by snow pit work shows that the DLP for λ \u003e 1.5 μm was very sensitive to large snow grains close to the surface. This finding suggests that polarization measurements obtained from airborne/satellite polarimeters will be useful for surface snow grain size retrievals and help improve the accuracy of such retrievals based on the intensity‐only measurements, especially for the large snow grain sizes.", "subitem_description_type": "Abstract"}]}, "item_3_full_name_183": {"attribute_name": "著者別名", "attribute_value_mlt": [{"affiliations": [{"affiliationNames": [{"affiliationName": "", "lang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "", "nameIdentifierScheme": "ISNI", "nameIdentifierURI": "http://www.isni.org/isni/"}]}], "familyNames": [{"familyName": "八久保", "familyNameLang": ""}, {"familyName": "八久保", "familyNameLang": ""}], "givenNames": [{"givenName": "晶弘", "givenNameLang": ""}, {"givenName": "晶弘", "givenNameLang": ""}], "nameIdentifiers": [{"nameIdentifier": "89765", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "50312450", "nameIdentifierScheme": "KAKEN - 研究者検索", "nameIdentifierURI": "https://nrid.nii.ac.jp/ja/nrid/1000050312450"}], "names": [{"name": "八久保, 晶弘", "nameLang": ""}, {"name": "八久保, 晶弘", "nameLang": ""}]}]}, "item_3_publisher_212": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "AGU Publications"}]}, "item_3_relation_191": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1002/2014JD022325", "subitem_relation_type_select": "DOI"}}]}, "item_3_select_195": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_3_source_id_187": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2169-897X", "subitem_source_identifier_type": "ISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right_uri": "open access"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tanikawa, Tomonori", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90380", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hori, Masahiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90381", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Aoki, Teruo", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90382", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hachikubo, Akihiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90383", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kuchiki, Katsuyuki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90384", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Niwano, Masashi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90385", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Matoba, Sumito", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90386", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamaguchi, Satoru", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90387", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Stamnes, Knut", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90388", "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": "2020-01-17"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "J.
