ALONG: Atlantic overturning circulation from GRACE/GRACE-FO
The Atlantic Meridional Overturning Circulation (AMOC) is a key element of heat transport in the Earth’s climate system. A slow-down would have significant impact, especially on our climate in Europe. Observations of AMOC changes, covering all of the Atlantic Ocean basin and for a substantially long time series, are so far not available. In this project, we propose to enhance the methodology to derive AMOC changes from satellite gravimetry and provide a time series of mass transport in the Atlantic Ocean, based on the full data record of the satellite missions GRACE and GRACE-FO. These novel observations will allow new insights into the AMOC through improved temporal and spatial coverage. Thus, we will make a substantial contribution to understanding and observing our changing climate, a topic which is of highest concern, both for science and society.
