Excerpt:
"The long-term goal of this focus area is to enable improved predictions of the global water and energy cycles. This key goal requires not only documenting and predicting means and trends in the rate of the Earth's water and energy cycling as well as predicting changes in the frequency and intensity of related meteorological and hydrologic events such as floods and droughts."
