ATLAS/ICESat-2 L3A Land and Vegetation Height, Version 5 (ATL08)
This is the most recent version of these data.
Changes for this version include:
- Added terrain_best_fit_geosegment parameter at the 20 m (geosegment) rate. This represents the best estimate of terrain at the 20 m along-track resolution.
- Added h_canopy_geosegment which represents the 20 m estimate of the 98% relative canopy height.
- Added latitude_20 and longitude_20 to the data product for geolocation of the 20 m terrain and canopy height estimates
- Added a segment_woody_vegetation_fractional cover to the ATL08 data product. This product is derived from the Copernicus fractional forest and fraction shrub data products
- Updated the segment_landcover with the 2019 Copernicus landcover. This update replaces the MODIS landcover value which was derived from the 2014 MODIS product. See the version section in the user guide for more information.
- Updated the urban_flag parameter with the DLR Global Urban Footprint (GUF) as a potential indicator of man-made/built structures. See the version section in the user guide for more information.
This data set (ATL08) contains along-track heights above the WGS84 ellipsoid (ITRF2014 reference frame) for the ground and canopy surfaces. 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.

Data Access & Tools
Product Specification Documents
This webinar introduces the ICESat-2 mission and shows you how to explore, access and customize ICESat-2 data with the OpenAltimetry application, using NSIDC DAAC tools, and shows you how to subset, reformat and analyze the data using Python.
Many NSIDC DAAC data sets can be accessed using the NSIDC DAAC's Data Access Tool. This tool provides the ability to search and filter data with spatial and temporal constraints using a map-based interface.
To convert HDF5 files into binary format you will need to use the h5dump utility, which is part of the HDF5 distribution available from the HDF Group. How you install HDF5 depends on your operating system.
This guide will provide an overview of the altimetry measurements and data sets across the missions, as well as a guide for accessing the data through NASA Earthdata Search and programmatically using an Application Programming Interface (API).
All data from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) can be accessed directly from our HTTPS file system, using wget or curl. Basic command line instructions are provided in the article below.
NASA Earthdata Search is a map-based interface where a user can search for Earth science data, filter results based on spatial and temporal constraints, and order data with customizations including re-formatting, re-projecting, and spatial and parameter subsetting.
This article covers frequently asked questions about the NASA NSIDC DAAC's Earthdata cloud migration project and what it means to data users.
The NASA Earthdata Cloud is the NASA cloud-based archive of Earth observations. It is hosted by Amazon Web Services (AWS). Learn how to find and access NSIDC DAAC data directly in the cloud.
The following table describes the subsetting and reformatting services that are currently available for ICESat-2 data via the NASA Earthdata Search tool, along with
