And GPM can do that because we are able to measure layer-by-layer within the storm and provide drop size distributions, not only of the rain particles, but also the snowflakes within that storm.

GPM 可以做到这一点，因为我们能够在风暴中逐层测量并提供雨滴大小的分布，不仅是雨粒子的分布，还包括风暴中雪花的分布。

In fact, the two radars on board the GPM satellite can also measure drop sizes from space and so a more accurate look at raindrops gives us a more accurate look at how global rainfall is shaping up.

事实上，GPM 卫星上的两个雷达也可以从太空测量雨滴的大小，因此更准确地观察雨滴可以让我们更准确地了解全球降雨是如何形成的。
