Projects > Water Cluster Portal

1. Overview

The water cycle delivers the consequences of climate change. In fact, Asrar et al., 2001 states that " the most significant manifestation of climate change for humans and the environment is an intensification of the global water cycle, leading to increased global precipitation, faster evaporation, and a general exacerbation of extreme hydrologic regimes, floods, and droughts". And the U.S. National Research Council report Research Pathways for the Next Decade recognized that "Water is at the heart of both the causes and the effects of climate change. It is essential to establish current rates of, and possible changes in precipitation, evapotranspiration, and cloud water content" (NRC, 1999). An intensified water and energy cycle would be expected to produce more frequent or severe weather disturbances. We have observed a significant global mean temperature increase over the last 20 years (Bengtsson et al. 1999), and United States precipitation has increased by about 10% during the last century, with much of the change resulting from heavy rainfall frequency and intensity increases (Morel, 2001).

Therefore, the Water Cluster Portal is proposed to use advancements in scientific observations and knowledge to develop solutions to society's water challenges, NASA's Earth science programs have collected substantial water cycle information and knowledge that must be integrated and shared to develop solutions in all twelve national priority application areas. However, NASA alone cannot achieve the ultimate goal of improved operational environmental assessments, predictions and applications and therefore we must establish collaborations and interoperability with existing research organizations, operational agencies, the scientific community, and end users.
