The Use of Gravimetry Satellites for Measuring Ice and Sea Level Change
Satellites now allow researchers to make more accurate mass measurements to large areas covered by ice and understand the effects of snow and ice melt on sea level change.
Measuring Small Variations in the Earth’s Gravity
The NASA–German Grace satellites were launched in May of 2002 in order to map variations in Earth’s gravity field.
Using Remote Sensing to Measure the Effect of Drought on Ground Water
This map shows a comparison of modeled relative amount of water stored in underground aquifers in the continental United States for July 7, 2014 as compared to the average for comparable weeks for the sixty year average water storage.
