Refined satellite imaging to measure geographic change

Changes in ice sheets, river basins and other geographic areas could now be recorded with more accuracy as Princeton University researchers have developed an approach to capturing refined satellite images.

The researchers can now clean up signal variations and distortions that obscure GRACE (Gravity Recovery And Climate Experiment) satellite readings.

The technique has already revealed sharper-than-ever details about Greenland’s massive ice sheet, suggesting that its melting may be accelerating more slowly than predicted.
