Version Summary
Initial release

Overview

ATL20QL is the quick look version of ATL20 and is based on the same algorithms that generate the ATL20 final data products. Once final ATL20 files are available, the corresponding ATL20QL files are removed. ATL20QL contains rolling 30-day gridded estimates of sea ice freeboard, derived from ATLAS/ICESat-2 L3A Sea Ice Freeboard Quick Look (ATL10QL) along-track freeboard estimates.
