Snow Data Assimilation System (SNODAS) Data Products at NSIDC, Version 1

Notice: Due to funding limitations, this data set was recently changed to a “Basic” Level of Service. Learn more about what this means for users and how you can share your story here: Level of Service Update for Data Products. This data set contains snow pack properties, such as depth and snow water equivalent (SWE), from the NOAA National Weather Service's National Operational Hydrologic Remote Sensing Center (NOHRSC) SNOw Data Assimilation System (SNODAS). SNODAS is a modeling and data assimilation system developed by NOHRSC to provide the best possible estimates of snow cover and associated parameters to support hydrologic modeling and analysis.注意：由于资金限制，本数据集近期已调整为「基础服务」等级。如需了解该调整对用户的具体影响，以及如何分享您的使用反馈，请访问此处：数据产品服务等级更新说明。 本数据集包含美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）国家气象局（National Weather Service）下属国家业务水文遥感中心（National Operational Hydrologic Remote Sensing Center, NOHRSC）的雪数据同化系统（SNOw Data Assimilation System, SNODAS）产出的积雪属性数据，例如积雪深度与雪水当量（snow water equivalent, SWE）。雪数据同化系统（SNODAS）是由NOHRSC开发的建模与数据同化系统，旨在提供尽可能精准的积雪覆盖范围及相关参数估算结果，以支撑水文建模与分析工作。
