As GRACE travels over areas of snow and ice sheets such as Greenland and Antarctica, changes in mass will be recorded. This information, along with measurements from the ground and other satellites will enable scientists to determine if these areas are growing or shrinking. Knowledge of this mass variation is key to understanding the effects of climate change and sea level rise.
