浙江省重大活动保障局地百米级多源融合分析产品

浙江省重大活动保障局地百米级多源融合分析产品（V1.0）面向我省局地重大活动气象保障服务需求，包含要素为10分钟累计降水、2m气温、10m风速和相对湿度，水平分辨率0.001°×0.001°，时间分辨率5分钟。产品采用国家气象信息中心数据研究室百米实况产品融合分析算法，包括物理统计降尺度、人工智能深度学习、多重网格变分和概率密度订正等融合技术。数据源中地面自动站分钟和小时数据经过了浙江省基于天擎的省级地面实时质量控制系统、X波段雷达经过了偏振参量和退速度模糊质量控制程序。产品可根据需求进行时间和空间定制。The Zhejiang Provincial 100-meter-scale Multi-source Fusion Analysis Product for Local Major Event Support (V1.0) is developed to meet the meteorological support service needs for local major events in Zhejiang Province. The product includes four core meteorological elements: 10-minute accumulated precipitation, 2-meter air temperature, 10-meter wind speed, and relative humidity. It has a horizontal resolution of 0.001° × 0.001° and a temporal resolution of 5 minutes. This product adopts the 100-meter-scale real-time product fusion analysis algorithm developed by the Data Research Laboratory of the National Meteorological Information Center, integrating fusion technologies such as physical statistical downscaling, artificial intelligence (AI) deep learning, multi-grid variational correction, and probability density correction. For its data sources, the minute and hourly data from automatic surface weather stations have undergone quality control via the Zhejiang Provincial Real-time Ground Quality Control System based on Tianqing, while X-band radars have been processed with quality control procedures including polarization parameter correction and velocity dealiasing. This product supports temporal and spatial customization based on user demands.
