Satellites Help Measure Earth's Water

Scientists say they've used satellite data to measure for the first time the amount of water that rises and falls in the Amazon River floodplain each year. Ohio State University researchers say the information is critical to predicting floods and droughts that might be brought about by global climate change.

Until now, researchers trying to estimate the amount of water in the Amazon floodplain and other river systems around the world had only a few sporadic field studies and crude assumptions to go on, the release said.

"Satellite observations are the only reliable option for places like the Amazon and especially the Congo Basin, where in-person measurements are near-impossible," Doug Alsdorf, OSU associate professor of earth sciences said.
