This algorithm has the advantage that it can be applied to any mixing condition of liquid and ice particles in clouds (i.e., pure-water clouds, pure-ice clouds, and mixed-phase clouds). To precisely treat the scattering processes of the radar waves in clouds, we pay attention to non-sphericity of ice-particles and radar wave attenuation by scattering, which are frequently neglected in the previous studies. The hexagonal ice-particles with various aspect ratios are considered. On the other hand, the observational data used in this algorithm need two assumptions: 1) the observed cloud does not contain precipitating and melting particles, and 2) the water vapor profiles are approximated by successive steady-state representations. The accuracy of the radar calibration required for this algorithm would be within +/- 0.1 dB, which is about the order of uncertainty of radar measurements. In the retrieval procedure, the mixing condition of water-droplets and ice-particles in the target cloud sub-layer can be identified by utilizing the wavelength-dependence of the scattering and attenuation properties. Once the mixing condition of the cloud sub-layer is determined, the microphysical properties of pure-water and pure-ice clouds are estimated by the algorithm, similar to the widely-used dual-wavelength technique, except for the fact that in the present algorithm, an equivalent aspect ratio of ice-particles can be estimated, in addition to ice-water-content and ice-particle size of pure-ice clouds. For mixed-phase clouds, the microphysical profiles, which satisfy the observed radar and microwave-radiometer signals, can be estimated by iteratively changing aspect ratios of ice-particles in each sublayer. The retrieval algorithm is applied to the observational data obtained in the Vertically Pointing Measurements, Tsukuba, 2001 (VPM_TKB01). The retrieved microphysical profiles for the pure-ice clouds show reasonable performance of the present algorithm, although there are no in-situ measurements to validate the estimated values.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "METEOROLOGICAL SOC JPN", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.2151/jmsj.84.1005"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0026-1165", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Yukio Yoshida", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Shoji Asano", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Koyuru Iwanami", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Retrieval of microphysical properties of water, ice, and mixed-phase clouds using a triple-wavelength radar and microwave radiometer", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Retrieval of microphysical properties of water, ice, and mixed-phase clouds using a triple-wavelength radar and microwave radiometer", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5535", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5535", "relation": {}, "relation_version_is_last": true, "title": ["Retrieval of microphysical properties of water, ice, and mixed-phase clouds using a triple-wavelength radar and microwave radiometer"], "weko_shared_id": -1}
