• On Wednesday, April 24, from 9:00 a.m. to 2:30 p.m. (US Mountain Time), the following data collections may not be available due to planned system maintenance: ASO, AMSR Unified, AMSR-E, Aquarius, High Mountain Asia, IceBridge, ICESat/GLAS, ICESat-2, LVIS, MEaSUREs, MODIS, Nimbus, SMAP, SnowEx, SSM/I-SSMIS and VIIRS.

  • The ICESat-2 Quick Look data sets are currently experiencing delays beyond the nominal 3-day latency. Issues at two ground stations are causing the delay and possible permanent data gaps. EDOS is actively working to resume nominal operations. We apologize for any inconvenience.

  • Beginning 25 May 2023, the sea ice concentration data product used in processing ATL07QL V6 and ATL10QL V6 was switched to Near-Real-Time NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration.

Overview

ATL10QL is the quick look version of ATL10. Once final ATL10 files are available the corresponding ATL10QL files will be removed. ATL10 contains estimates of sea ice freeboard, calculated using three different approaches. Sea ice leads used to establish the reference sea surface and descriptive statistics used in the height estimates are also provided. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) observatory.
