Satellites Find Balance

February 9, 2007 at 1:12 pm Leave a comment

In 2006 NASA scientists used satellite technology to measure and monitor the water cycle of the entire South American continent. The monitoring and research found that the amount of water the continent receives from rain and snow is in balance with the amount of water that leaves the land through runoff and rivers flowing into the ocean. Scientists can now use this information to monitor the balance of water on the continent and better understand cycles of drought and floods. According to Dr. Timothy Liu, a scientist at NASA’s Jet Propulsion Laboratory (JPL), “We’ll have greater understanding of floods and drought, surface and ground water, and the availability of freshwater resources for agriculture and ecosystems.” The study is showing how important satellite based imagery can contribute to understanding the earth’s ecosystem.

More information can be found at JPL’s website.
