This is the most recent version of these data.
Version Summary
Version Summary
-Introduced interpolation of reference surface heights when computing freeboard heights. In previous releases, a static value of the 10 km reference surface was used to compute freeboard heights. In v7, reference surface heights are interpolated (if neighboring reference surfaces are available) to the freeboard height location before freeboard height computation.
-Introduced option to include heights computed using a lognormal distribution when available.
-Fixed oc_depth parameter. Previously, oc_depth only had values of 0.0.

Overview
ATL10QL is the quick look version of ATL10 and is based on the same algorithms that generate the ATL10 final data products. Once final ATL10 files are available, the corresponding ATL10QL files are removed. ATL10 contains along-track sea ice freeboard calculated for 10 km swath segments. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the ICESat-2 observatory.
