Fig. 2. Lake level variation of Lake Nasser from satellite altimetry (LEGOS/GOHS) (reference point: ¢ = 22.60°,A = 32.10°). where Nagwin Stands for the contribution of the window-reduced gravity In the context of the remove-restore technique (Forsberg, 1984), a set of fine and coarse DHMs is needed for the terrain reduction com- putation. The 3” x 3” fine Digital Height Model EGH13S03 and the 30” x 30” coarse Digital Height Model EGH13S30 (Abd-Elmotaal et al., 2013) are available for this investigation. These DHMs cover the full window of (19°N < ¢ < 35°N;22°E <A < 40°F). Fig. 3 illustrates the 3” x 3" fine EGH13S03 for the Lake Nasser area
