NASA: Ice Sheets
Data from NASA's GRACE and GRACE Follow-On satellites show that the land ice sheets in both Antarctica (upper chart) and Greenland (lower chart) have been losing mass since 2002. The GRACE mission concluded science operations in June 2017.
GRACE Follow-On began data collection in June 2018 and is now continuing the mass change data record for both ice sheets. This data record includes the latest data processing improvements and is continuously updated as more data are collected (with a lag of up to two months).
