NASA is tracking Earth's changing water cycle


Today’s Video of the Day from NASA Goddard Space Flight Center explains how research and satellite data from NASA can help government agencies manage water resources. 

Freshwater rivers and lakes provide two-thirds of the drinking water in the United States, yet rainfall and snowmelt patterns are becoming less predictable with climate change. 

NASA has been consistently expanding its view of how fresh water moves around the planet since the 1960s.

These observations provide powerful tools for scientists to study the water cycle and to predict how it will affect water supplies in a warming climate.
