Version Summary
Version Summary
Added starting along-track distance of sea-ice segment to main data group. Average along-track distance remains on product; Introduced lognormal distributions to be used as alternate expected waveform table; Implemented the option to process sea ice heights at half-stepping, 10-meter segment lengths; Introduced DDA-Bifurcation algorithm, which provides independently computed heights along with the ATL07 heights and helps detect and measure potential melt ponds; Updated algorithm to apply Dynamic Atmosphere Correction (DAC) as a geophysical correction; Introduced new fine-tracker algorithm to make it modular and introduce custom data groups to help with data handling and writing.
Overview
ATL07 contains along-track sea surface height and sea ice height for segments of variable lengths for all beams as well as fixed 10-meter segments for strong beams. Heights are also computed using the DDA-Bifurcation algorithm for strong beams. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the ICESat-2 observatory.
