Here, we propose a new method referring to the inner pressure at the nadir of a balloon. The inner pressure is approximately proportional to the amount of descent from the level altitude and to the atmospheric pressure at the level altitude. This method has advantages in its simplic- ity and does not require prior information of the level altitude.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006290","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":"AA11397422","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":"Institute of Space and Astronautical Science/Institute of Space and Astronautical Science/Yamagata Academy of Engineering"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1999-09-01"}],"displaytype":"detail","filename":"KJ00000048030.pdf","filesize":[{"value":"967.8 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000048030","url":"https://nipr.repo.nii.ac.jp/record/6290/files/KJ00000048030.pdf"},"version_id":"4e74db18-8a97-4ac8-945d-bab9c678085e"}]},"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":"Automatic ballast control referring to the inner pressure at the nadir of the balloon","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Automatic ballast control referring to the inner pressure at the nadir of the balloon"}]},"item_type_id":"1","owner":"4","path":["803"],"pubdate":{"attribute_name":"公開日","attribute_value":"1999-09-01"},"publish_date":"1999-09-01","publish_status":"0","recid":"6290","relation_version_is_last":true,"title":["Automatic ballast control referring to the inner pressure at the nadir of the balloon"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:03:27.076568+00:00"}
