全球表面实况分析产品

全球表面实况分析产品（V1.0）是基于全球大气实况分析系统输出的短期预报值作为背景场，利用集合卡尔曼滤波同化算法，融合全球地面（含中国国家站地面）、机场、船舶、浮标等常规观测资料和METOP/ASCAT卫星反演洋面风产品，计算得到的全球同化分析产品，产品空间分辨率10km，时间分辨率3小时。

Global Surface Reanalysis Product (V1.0) is a global assimilation analysis product developed based on the short-term forecast outputs of the Global Atmospheric Reanalysis System as the background field, using the ensemble Kalman filter assimilation algorithm to fuse conventional observation data including global surface (including surface data from China's national meteorological stations), airports, ships, buoys and other sources, as well as sea surface wind products retrieved by METOP/ASCAT satellites. The product has a spatial resolution of 10 km and a temporal resolution of 3 hours.
