Cloud phase affects on the microphysics, however the knowledge in the Arctic region is limited because of dry atmosphere and high surface. Polarized micro-pulse lidar (PMPL) at Ny-Alesund, Svalbard (78˚56’N, 11˚52’, 40m a.s.l.) installed by the National Institute of Polar Research (NIPR) in 2013 has capability of high-accuracy and -resolution observation of vertical distributions of aerosol and cloud. PMPL also retrieves the particle-shape information by depolarization of the backscatter. This study analyzed phase of cloud base and the dependency on temperature with observation data of PMPL. Ratio of ice-containing cloud at base altitude shows the linear relationship with cloud base temperature. In comparison with the previous study about the frequency appearance of ice cloud in the other regions, the results correspond to the present study.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"Polar Meteorology and Glaciology Group seminar / 気水圏コロキウム \n日時：3月8日（水）10:00-10:50 \n場所：C301（3階セミナー室）","subitem_description_type":"Other"}]},"item_10005_text_18":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"国立極地研究所"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, 恭平"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"偏光マイクロパルスライダー"},{"subitem_subject":"ニーオルスン"},{"subitem_subject":"polarized micro-pulse lidar","subitem_subject_language":"en"},{"subitem_subject":"Ny-Alesund","subitem_subject_language":"en"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"偏光MPLを用いたニーオルスン上空の氷雲出現の雲底温度依存性に関する解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"偏光MPLを用いたニーオルスン上空の氷雲出現の雲底温度依存性に関する解析"},{"subitem_title":"Analysis of dependency of ice-cloud on cloud base temperature with the polarized micro-pulse lidar over Ny-Alesund","subitem_title_language":"en"}]},"item_type_id":"10005","owner":"17","path":["1817"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-03-08"},"publish_date":"2017-03-08","publish_status":"0","recid":"14122","relation_version_is_last":true,"title":["偏光MPLを用いたニーオルスン上空の氷雲出現の雲底温度依存性に関する解析"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-07-25T15:24:44.095644+00:00"}
