在多雪地区寻找淡水
覆盖在山脉上或堆积于树冠下的雪花是全世界超过10亿人口的重要淡水资源。为了帮助确定雪中储存了多少淡水，NASA资助的研究小组正在开发一种基于计算机的工具，对从太空中识别雪并测量其含水量的最佳方法进行模拟。

Snowflakes that cover mountains or linger under tree canopies are a vital freshwater resource for over a billion people around the world. To help determine how much freshwater is stored in snow, a team of NASA-funded researchers is creating a computer-based tool that simulates the best way to detect snow and measure its water content from space.
