In-situ sea ice thickness samples were obtained from video observations by the icebreaker Soya during 1996-1998 and surface feature observations in 1997 by the visible and near-infrared radiometer AVNIR mounted on the ADEOS satellite. These sea ice thickness data were binned into grid cell data of the satellite microwave radiometer SSM/I for the same location, and averaged to provide an average ice thickness for a grid cell. In order to survey the relationship between sea ice thickness and microwave radiation, two sea ice classification parameters for SSM/I were investigated as to their ability to estimate sea ice thickness. One sea ice classification parameter is the Polarization Ratio (PR), which was developed for a seasonally ice covered area and can distinguish three ice types: new ice, young ice, and first-year ice. Another parameter is the ratio between 37GHz vertical polarization and 85GHz vertical polarization (R_<37V/85V>). It can distinguish fast ice in addition to the three ice types that can be distinguished by the PR. These parameters showed correlation coefficients with in-situ sea ice thickness, -0.77 and 0.67, respectively, in this study. Estimated sea ice thickness derived from multiple regression analysis using PR and R_<37V/85V> showed good correlation (R=0.81) with in-situ sea ice thickness.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002943","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA1129795X","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Sea Ice Research Laboratory, Institute of Low Temperature Science, Hokkaido University"},{"subitem_text_language":"en","subitem_text_value":"Department of Civil Engineering, Kitami Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Institute of Low Temperature Science, Hokkaido University"},{"subitem_text_language":"en","subitem_text_value":"National Maritime Research Institute"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2002-11-01"}],"displaytype":"detail","filename":"KJ00000043816.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000043816","url":"https://nipr.repo.nii.ac.jp/record/2943/files/KJ00000043816.pdf"},"version_id":"a8756e86-16ab-4b35-ae16-9d0e6a76c567"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Sea ice thickness estimated from passive microwave radiometers","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Sea ice thickness estimated from passive microwave radiometers"}]},"item_type_id":"1","owner":"4","path":["430"],"pubdate":{"attribute_name":"公開日","attribute_value":"2002-11-01"},"publish_date":"2002-11-01","publish_status":"0","recid":"2943","relation_version_is_last":true,"title":["Sea ice thickness estimated from passive microwave radiometers"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:40:13.037433+00:00"}
