Preliminary results of two case studies, the mountain enhanced rainfall case and the fast moving rain cell case, suggest several advantages of MP-X radar estimates. First, the accuracy of MP-X radar is higher than that of Radar-AMeDAS over mountainous area where available raingauges are limited in the Radar-AMeDAS estimates. Second, the temporal and space resolution of MP-X radar data is better than Radar-AMeDAS data: MP-X radar has 1 minute time resolution and 500m space resolution while Radar-AMeDAS has 30 minute time resolution and 2.5km space resolution. Results of analysis of the fast moving rain cells case show MP-X radar detected the rainfall trajectory of a strong rain cell (maximum hourly rainfall amount about 70 mm was observed), which has 3 km in width and about 40km in length, while the Radar-AMeDAS overlooked it.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "水文・水資源学会", "subitem_publisher_language": "ja"}, {"subitem_publisher": "THE JAPAN SOCIETY OF HYDROLOGY AND WATER RESOURCES", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.11520/jshwr.18.0.124.0"}}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "真木 雅之", "creatorNameLang": "ja"}, {"creatorName": "M.
