Description

ATL11XO provides slope-corrected land ice surface heights at points where ATL06 (ATLAS/ICESat-2 L3A Land Ice Height) tracks cross ATL11 (ATLAS/ICESat-2 L3B Slope-Corrected Land Ice Height Time Series) tracks, allowing direct comparisons between ATL06 and ATL11 elevations and facilitating dense height time series that span the entire ICESat-2 mission.
