NASA expands groundwater map from U.S. to global

NASA, in collaboration with the National Drought Mitigation Center at the University of Nebraska-Lincoln, has released maps showing groundwater and soil moisture and predictions for its future around the world,media reported. This marks an important extension of the map — from the United States to the world — to draw attention to remote and rural areas where drought and other water problems may not be easy to detect.

NASA expands groundwater map from U.S. to global

The GRACE-FO satellite from NASA and the German Centre for Geosciences is understood to have made this expansion possible. The satellite’s data is combined with other data and computer models to demonstrate energy and water cycle simulations around the world.

The map provides moisture data for three layers of soil, namely surface soil moisture content, root moisture content, and shallow groundwater. With this in mind, experts can monitor groundwater conditions around the world and determine which areas may be severely affected by drought. This is particularly important in countries that do not have the infrastructure to monitor groundwater.

With climate change and global warming, drought has become a growing problem. By observing current water conditions and predicting how it will develop, it will help Governments around the world to take effective offset measures in a timely manner.

It is reported that anyone can access and download the project’s groundwater map through the UNL-operated NASA Grace website.
