From: Human alteration of global surface water storage variability

Extended Data Fig. 6

a, For pairs of dates with both ICESat-2 observations and CDWR storage estimates for the same lake, we calculate the difference in storage observed by ICESat-2 by multiplying the height change by our lake area estimate from the water-body mask and compare this to the CDWR storage change between these two dates. b, A histogram of the difference between our ICESat-2-derived and CDWR storage estimates. Overall, we find great agreement between our storage change estimates and those observed by CDWR. Considering that both our height and area measurements are derived independently of those used by CDWR, the strong agreement emphasizes the robustness of our method.
