Alaska Satellite Facility

The Alaska Satellite Facility is a data processing facility and satellite-tracking ground station within the Geophysical Institute at the University of Alaska Fairbanks. The facility’s mission is to make remote-sensing data accessible. Its work is central to polar processes research including wetlands, glaciers, sea ice, climate change, permafrost, flooding and land cover such as changes in the Amazon rainforest. The ASF DAAC is one of the Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Centers (DAACs) that archive and distribute earth science data, managed by NASA's Earth Science Data and Information System Project (ESDIS), as part of the Earth Science Data Systems (ESDS) Program.

阿拉斯加卫星设施（Alaska Satellite Facility, ASF）是阿拉斯加大学费尔班克斯分校地球物理研究所下属的数据处理设施与卫星跟踪地面站。该机构的使命是推动遥感数据的开放获取。其研究工作核心支撑极地过程研究领域，涵盖湿地、冰川、海冰、气候变化、永久冻土、洪涝灾害以及土地覆盖变化（如亚马逊雨林变迁）等方向。ASF DAAC是地球观测系统数据与信息系统（Earth Observing System Data and Information System, EOSDIS）下属的分布式主动存档中心（Distributed Active Archive Centers, DAACs）之一，其职能为存档与分发地球科学数据；该中心由美国国家航空航天局（NASA）地球科学数据与信息系统项目（Earth Science Data and Information System Project, ESDIS）管理，隶属于地球科学数据系统（Earth Science Data Systems, ESDS）计划。
