The canopy and ground surfaces are processed in fixed 100 m data segments, which typically contain more than 100 signal photons. 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.</Abstract></Summary><Related_URL><URL_Content_Type><Type>VIEW RELATED INFORMATION</Type></URL_Content_Type><URL>https://nsidc.org/sites/default/files/documents/user-guide/atl08-001-userguide.pdf</URL><Description>ATLAS/ICESat-2 L3A Land and Vegetation Height, Version 1 User Guide</Description></Related_URL><Metadata_Name>CEOS IDN DIF</Metadata_Name><Metadata_Version>VERSION 9.9</Metadata_Version><DIF_Creation_Date>2019-05-28</DIF_Creation_Date><Last_DIF_Revision_Date>2026-03-30</Last_DIF_Revision_Date><Extended_Metadata><Metadata><Group>NSIDC</Group><Name>Version Summary</Name><Value>Initial release</Value></Metadata><Metadata><Group>NSIDC</Group><Name>Minor Version</Name><Value/></Metadata><Metadata><Group>NSIDC</Group><Name>Spatial Reference Systems</Name><Value><Spatial_Reference_System><SRID>EPSG:4326</SRID><Description>WGS 84</Description></Spatial_Reference_System></Value></Metadata><Metadata><Group>NSIDC</Group><Name>Level of Service</Name><Value><Level>No Data Access</Level></Value></Metadata><Metadata><Group>NSIDC</Group><Name>Full Dataset Citation</Name><Value>Neuenschwander, A.
