Scientists from the German GFZ and French LEGOS/GOHS and CNES have jointly analyzed gravity data from GRACE, altimetry data and precipitation measurements over the Great Lakes region of East Africa to observe variability in terrestrial water storage, lake water volume and rainfall. Variability at interannual time scales, with a minimum in late 2005, followed by a rise in 2006 to 2007 is evident.
