The RMSE and statistics for different cross-validation. (a–c) RMSE between in-box ICESat-2 observations and the SIT reconstructed from out-of-box data. (d–f) SIT variability (standard deviation; STD) and (g–i) number of observations, respectively, for regions centered on the box shown in Fig. 4, expanded to four times the area. The number of observations was normalized using min-max scaling. Larger values are represented by larger circles with colors closer to green. The abbreviations “B-A,” “W-W,” “E-W,” “I-O,” “P-O,” and “Ross” are the same as in Fig. 4.
