Description

This data set (ATL02) contains science-unit-converted time-ordered telemetry data, calibrated for instrument effects, downlinked from the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) observatory. The data are used by the ATLAS/ICESat-2 Science Investigator-led Processing System (SIPS) for system-level, quality control analysis and as source data for ATLAS/ICESat-2 Level-2 products and Precision Orbit Determination (POD) and Precision Pointing Determination (PPD) computations.

Version Description

The following changes were implemented in Version 6 of the data set:
<ul>
<li>Corrected the implementation of the computation of receiver sensitivity as a function of transmit/receive misalignment</li>
<li>Updated calibration data products that affect the computation of time of flight, i.e., delay line cell widths, receiver channel skews, and start skews.</li>
</ul>
