abstract = "{Inter-annual trends in terrestrial water storage (TWS) were extracted
from monthly (01/2003-09/2012) Gravity Recovery and Climate
Experiment (GRACE) data acquired over Africa and correlated (in
a geographic information system [GIS] environment) with relevant
temporal remote sensing, geologic, and hydrologic datasets.
Findings include the following: (1) large sectors of Africa are
undergoing statistically significant TWS variations (+ 44 mm/yr
to - 15 mm/yr) due to natural and anthropogenic causes; (2)
warming of the tropical Atlantic Ocean apparently intensified
Atlantic monsoons and increased precipitation and TWS over
western and central Africa; (3) warming in the central Indian
Ocean decreased precipitation and TWS over eastern Africa; (4)
the high frequency of flooding events increased TWS over the
Zambezi and Okavango basins; (5) extraction of fossil
groundwater decreased TWS over the Saharan aquifers; (6)
deforestation decreased TWS in three subbasins (Ubangi, Congo,
and Sangha) of the Congo River Basin; and (7) the construction
of dams increased TWS in the Blue Nile and Atbara subbasins.
Given the 10 years of monthly GRACE data acquired on the
subbasin scale across the globe, as well as the plans underway
for deployment of a GRACE-FO and GRACE-II, using GRACE-derived
TWS data should be considered an alternative, viable index for
measuring temporal and spatial variations in water availability.}",
