The sonde consists of an expansion fog chamber, which is similar in principle to the Pollak counter or the Aitken counter, as a measuring device of Aitken unclei concentration. The most important characteristics of the present fog chamber are that it is a very compact automatic one and it has a construction to keep expansion ratio constant irrespective of ambient pressure. The constant expansion ratio is an essential requirement for the measurement of Aitken nuclei concentration at different heights by a balloon or an airplane. The variation of measured values during 50 times measurement for a same air sample is smaller than 3% of the mean. Two identical fog chambers in the present sonde give Aitken unclei concentrations which agree within 50(cm)^<-3> for the concentration range covering between about 200 and about 2000cm^<-3>. A nuclei measuring signal is inserted into rawinsonde signal, which is transmitted to a ground station, every minute for 10s. The total weight of a sonde is 9kg, comprising a 5kg fog chamber, a 3.5kg battery and a 0.5kg rawinsonde.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","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":"Meteorological Research Institute"},{"subitem_text_language":"en","subitem_text_value":"Meteorological Research Institute"},{"subitem_text_language":"en","subitem_text_value":"Meteorological 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":"1983-11-01"}],"displaytype":"detail","filename":"KJ00000012146.pdf","filesize":[{"value":"545.8 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012146","url":"https://nipr.repo.nii.ac.jp/record/1513/files/KJ00000012146.pdf"},"version_id":"fcfe8cbd-17c7-440a-83c6-7c2bac9ba2c8"}]},"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":"Aitken nuclei sonde with constant expansion ratio irrespective of ambient pressure","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Aitken nuclei sonde with constant expansion ratio irrespective of ambient pressure","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["383"],"pubdate":{"attribute_name":"公開日","attribute_value":"1983-11-01"},"publish_date":"1983-11-01","publish_status":"0","recid":"1513","relation_version_is_last":true,"title":["Aitken nuclei sonde with constant expansion ratio irrespective of ambient pressure"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:41:29.661830+00:00"}
