Description

This data set (ATL14) and ATL15 bring the time-varying height estimates provided in ATLAS/ICESat-2 L3B Annual Land Ice Height (ATL11) into a gridded format. ATL14 is a high-resolution (100 m) digital elevation model (DEM) that provides spatially continuous gridded data of ice sheet surface height. 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).

ATL15 provides coarser resolution (1 km, 10 km, 20 km, and 40 km) height-change maps at 3-month intervals, allowing for visualization of height-change patterns and calculation of integrated regional volume change.

Version Description

The changes from Versions 1 to 2 include the following:
  • Extend temporal coverage through cycle 14
  • Include one independent bias parameter for each RGT, cycle, and beam pair in the bias model
  • In all regions except Antarctica, use minimum error estimate for every unique crossover
  • Apply a time-variable ice mask, as reflected in the ice_area variable
  • Achieve tile-to-tile matching using linear constraint at tile edges
  • Decrease computation tile size to 61x61 km, and compute tiles in two stages instead of three
