This is the most recent version of these data.
Version Summary
Version Summary
Version 4 was derived from ATL11 Version 6 and includes the following changes:
-Extend temporal coverage through cycle 21
-Relax constraints for higher velocity ice sheets in Greenland
-Smooth error estimates before interpolation to correct for zero error conditions reported
-Correct longitude metadata extents for Antarctic regions
-Remove data from cycle 1 (Quarter 4 of 2018) to avoid artifacts from previous geolocation challenges

Overview
This data set contains a high-resolution (100 m) gridded digital elevation model (DEM) for the Antarctic ice sheet and regions around the Arctic. The data can be used to initialize ice sheet models, as boundary conditions for atmospheric models, or to help with the reduction of other satellite data such as optical imagery or synthetic aperture radar (SAR). The data are derived from the ATLAS/ICESat-2 L3B Slope-Corrected Land Ice Height Time Series product (ATL11).
