NASA WLDAS Project

The Western Land Data Assimilation System (WLDAS), developed at Goddard Space Flight Center (GSFC) and funded by the NASA Western Water Applications Office, provides water managers and stakeholders in the western United States with a long-term record of near-surface hydrology for use in drought assessment and water resources planning. WLDAS leverages advanced capabilities in land surface modeling and data assimilation to furnish a system that is customized for stakeholders’ needs in the region. WLDAS uses NASA’s Land Information System (LIS) to configure and drive the Noah Multiparameterizatio...由戈达德太空飞行中心（Goddard Space Flight Center，GSFC）开发、美国国家航空航天局（National Aeronautics and Space Administration，NASA）西部水应用办公室资助的西陆数据同化系统（Western Land Data Assimilation System，WLDAS），可为美国西部的水资源管理者与利益相关方提供长期近地表水文数据集，用于干旱评估与水资源规划。该系统依托先进的陆面建模与数据同化技术，构建了适配该区域利益相关方需求的定制化系统。WLDAS采用NASA的陆面信息系统（Land Information System，LIS）进行配置并驱动Noah多参数化（……）
