Delivery of Suomi National Polar-orbiting Partnership (Suomi NPP) satellite data products will cease on November 1, 2026. Data users should transition now to alternative products from NOAA-21 and NOAA-20.Suomi NPP data announcement
Description
ATL06 contains geolocated land-ice surface heights above the WGS84 ellipsoid, plus ancillary parameters that can be used to interpret and assess the quality of the height estimates. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the ICESat-2 observatory.
Version Description
-Removed backup signal finder from ATL06 algorithm.
-Added fpb_warning_flag variable to indicate ATL06 segments that could be impacted by signal saturation and for which the first-photon bias correction has failed.
