The instrumented balloon measured the particle size distribution, ice crystal images, dew/frost point, relative humidity, and temperature. The Raman lidar measured the particle backscattering and extinction coefficients and the depolarization ratio at a wavelength of 532 nm. The results of the balloon measurements showed that supermicrometer (0.7 to 2.8 mu m in optical-equivalent radius) dust particles and ice crystals (10 to 400 mu m in maximum dimension) were present in the upper troposphere (8 to 12 km in altitude), with number concentrations varying from 5 x 10(-3) to 0.6 cm(-3) for dust and from 5 x 10(-3) to 0.15 cm(-3) for ice crystals. The Raman lidar measurement indicated that the particle depolarization ratios were 15 to 35% in the altitude range of 6 to 12 km, indicating the predominance of nonspherical particles in the region. The temperature ranged from -33 to -63 degrees C, and the relative humidity with respect to ice (RHi), estimated from the total (vapor plus condensate) water content obtained with the Snow White hygrometer in the cloud, was 130% at maximum on 9 May, which was close to the activation point of Asian mineral dust as ice nuclei to form ice crystals.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "AMER GEOPHYSICAL UNION", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1002/2013JD020987"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2169-8996", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tetsu Sakai", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Narihiro Orikasa", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Tomohiro Nagai", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Masataka Murakami", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takuya Tajiri", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Atsushi Saito", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Katsuya Yamashita", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Akihiro Hashimoto", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Balloon-borne and Raman lidar observations of Asian dust and cirrus cloud properties over Tsukuba, Japan", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Balloon-borne and Raman lidar observations of Asian dust and cirrus cloud properties over Tsukuba, Japan", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/2711", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "2711", "relation": {}, "relation_version_is_last": true, "title": ["Balloon-borne and Raman lidar observations of Asian dust and cirrus cloud properties over Tsukuba, Japan"], "weko_shared_id": -1}
