Table S1. Statistics of the co-registration statistics between the external DEMs and the ICESat-2 snow-off DEM.-- Table S2. Statistics of the snow depth residuals for different snow-off Digital Elevation Models (DEMs) on 12 March 2019. The ICESat-2-ASO product is shown in detail on Figure 3. All residuals are shown in Figure 5 and S4.-- Table S3. Statistics of the co-registration statistics between the Pléiades and Copernicus DEMs to the ASO DEM at15 m. All these DEMs were previously co-registered to the ICESat-2 snow-off points.-- Figure S1. Map of the mean annual snow cover duration in the upper Tuolumne basin calculated from a time series of MODIS images (MOD10A1).-- Figure S2. Optimization of the kappa index to determine the photon count threshold defining snow-on and snow-off points based on MODIS snow cover area data.-- Figure S3. Vertical uncertainty of the ATL06 elevation (sigma_h_mean) against along-track slope (dh_fit_dx). The along-track slope (dh_fit_dx) is directly provided in ATL06.-- Figure S4. Same figure as Figure 5 but with snow depth derived from ICESat-2 and the ASO DEM (green, identical to Fig. 5) and ICESat-2 and the Copernicus DEM (purple). Note the different y-scale compared to Figure 5.-- Figure S5. Same as Figure 5 but selecting ICESat-2 ATL06 snow-on points of the strong beams only.-- Figure S6. Same as Figure 5 but selecting ICESat-2 ATL06 snow-on points of the weak beams only.-- Figure S7. Same as Figure 5 but calculating the relative snow depth error (ICESat-2 derived snow depth minus ASO snow depth divided by ASO snow depth) rather than the absolute snow depth error (ICESat-2 derived snow depth minus ASO snow depth).-- Figure S8. Distribution of the snow-off residual (ICESat-2 minus DEM) before (black line) and after coregistration (color) for the ASO DTM (left), the Pléiades DEM (middle) and the Copernicus DEM (right). The vertical lines show the median plus/minus the NMAD after coregistration.-- Figure S9. Snow depth (colored boxes) and snow-off (white boxes) residuals for ...
