Extended Data Fig. 4: Evaluation of ICESat-2 height retrievals against in situ gauge measurements.
From: Human alteration of global surface water storage variability
Each point represents a temporal change in height between two dates from both ICESat-2 and gauge measurements. a, b, Plots of ICESat-2 height difference against the corresponding gauge height difference; b shows a magnified version (ranging from −1 to 1 m) of a. c, Histogram of the difference between ICESat-2 and USGS gauge measurements. Overall, we find very good agreement between ICESat-2 and gauge measurements, with an MAE of 0.14 m and a mean bias of −0.019 m.
