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
Scientists can create higher resolution maps showing small variations in the earth’s gravity gradient by combining data from two different satellites. The NASA–German Grace satellites were … Read more
