How do we measure rainfall? (Frontiers for Young Minds, 2018, August 14)
Rainfall is both a needed resource, since it fills rivers and provides fresh water, and a potential threat with heavy rainfall leading to (possibly rapid) flooding. A much needed step to understand better this natural phenomenon is to properly measure it. It turns out to be pretty tricky because rainfall is extremely variable in time and space. In this paper, you will learn the functioning of three rainfall measurement devices providing cumulative rainfall depth (tipping bucket rain gauges), size and velocity of falling drops (disdrometers), or rainfall maps (weather radars).
