The time series of brightness temperature (Tb) at 19 GHz and 37GHz, their gradient ratio (GR : 37 GHz minus 19 GHz) and polarization at each frequency were analyzed. Tb does not reflect simply the air temperature, but it reflects the GR value. The lowest GR is observed in the ridge area of East Antarctica. GR alters its sign with season, that is, it is positive in summer and negative in winter; lower frequency indicates the temperature of the deeper snow layer. However, GR in the ridge area shows negative values throughout the year. Results of the polarization also show distinct seasonal changes between the ridge area and the lower part of the ice sheet. It is concluded that there is high variability of microwave signals along the traverse route between Syowa Station and Dome Fuji Station, which may imply that altitudinal variations of snow characteristics are large in this region.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003954","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":"AA10756213","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":"Kitami Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Sendai College of Technology"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ABSTRACT"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1996-09-01"}],"displaytype":"detail","filename":"KJ00000768015.pdf","filesize":[{"value":"59.8 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000768015","url":"https://nipr.repo.nii.ac.jp/record/3954/files/KJ00000768015.pdf"},"version_id":"0b471a76-18bf-48fa-af48-13de5b119f35"}]},"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":"TEMPORAL VARIATIONS OF PASSIVE MICROWAVES FROM THE ICE SHEET","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"TEMPORAL VARIATIONS OF PASSIVE MICROWAVES FROM THE ICE SHEET"}]},"item_type_id":"1","owner":"4","path":["534"],"pubdate":{"attribute_name":"公開日","attribute_value":"1996-09-01"},"publish_date":"1996-09-01","publish_status":"0","recid":"3954","relation_version_is_last":true,"title":["TEMPORAL VARIATIONS OF PASSIVE MICROWAVES FROM THE ICE SHEET"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:25:59.200722+00:00"}
