Data Announcement

New data set release: ICESat-2 Derived 30 m Along-Track Boreal Aboveground Biomass Density, Version 01

ICESat-2 Derived 30 m Along-Track Boreal Aboveground Biomass Density, Version 01 is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).  This data set provides a quality-filtered set of ATLAS/ICESat-2 L3A Land and Vegetation Height (ATL08), Version 5 observations of relative canopy heights and aboveground biomass density model results for circumpolar boreal forests.  The data were collected at 30 m along-track segment lengths during the 2019–2021 high northern latitude growing seasons.
