Data Set ID:
ATL09QL
Data Set Summary:
ATL09QL is the quick look version of ATL09 and is based on the same algorithms that generate the ATL09 final data products. Once final ATL09 files are available, the corresponding ATL09QL files are removed. ATL09QL contains calibrated, attenuated backscatter profiles (CAB), layer-integrated attenuated backscatter, blowing snow, and other parameters including cloud and aerosol layer height and atmospheric characteristics. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the ICESat-2 observatory.
