Gravity Recovery and Climate Experiment (GRACE) solutions of
surface water mass change have been computed over Africa from
2003 to 2012 with a 10-day resolution by using a new regional
approach. These regional maps are used to describe and quantify
water mass change. The contribution of African hydrology to
actual sea level rise is negative and small in magnitude (i.e.,
-0.1 mm/y of equivalent sea level (ESL)) mainly explained by the
water retained in the Zambezi River basin. Analysis of the
regional water mass maps is used to distinguish different zones
of important water mass variations, with the exception of the
dominant seasonal cycle of the African monsoon in the Sahel and
Central Africa. The analysis of the regional solutions reveals
the accumulation in the Okavango swamp and South Niger. It
confirms the continuous depletion of water in the North Sahara
aquifer at the rate of -2.3 km$^{3}$/y, with a decrease in early
2008. Synergistic use of altimetry-based lake water volume with
total water storage (TWS) from GRACE permits a continuous
monitoring of sub-surface water storage for large lake drainage
areas. These different applications demonstrate the potential of
the GRACE mission for the management of water resources at the
regional scale.}",
