Version Summary
Version Summary
Changes for this version include:
- The Arctic and Antarctic DEMs were changed to utilize sources that have more recent and accurate data and better coverage.
- The num_tx_pulses calculation was changed to estimate an expected number of pulses that is not an integer. As such, the input used to calculate num_tx_pulses was changed to a floating point value (the output of the unified pulse count estimation).
- A single algorithm was implemented to estimate the number of pulses within a specified distance, and this single routine was integrated into the rest of the land ice height development code.
- Equilibrium tide values from ATL03 have been added to the geophysical group (gt[x]/land_ice_segments/geophysical/tide_equilibrium).
Overview
This data set (ATL06) provides geolocated, land-ice surface heights (above the WGS 84 ellipsoid, ITRF2014 reference frame), plus ancillary parameters that can be used to interpret and assess the quality of the height estimates. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) observatory.
