美欧卫星将进行世界上第一次全球淡水调查
一旦卫星进入轨道，SWOT任务不仅将定期监测像俄勒冈州威拉米特这样的强大河流（如图），而且还将监测直径至少330英尺(100米)的小河流。 影像来源：美国能源部 地表水和海洋地形任务将对地球上95%以上的湖泊、河流和水库进行测量。 水就是生命，但尽管水很重要，但人类对地球淡水体的看法却出奇地有限。研究人员对全球仅有的几千个湖泊进行了可靠的水位测量，而地球上一些重要的河流系统几乎没有数据。即将到来的地表水和海洋地形（SWOT）卫星将填补这一巨大空白。通过帮助人们更好地了解地球的水循环，它将有助于更好地管理水资源，并扩大对气候变化如何影响湖泊、河流和水库的知识。 由NASA和法国航天局国家空间研究
