With the migration of GLAS/ICESat data to the NASA Earthdata Cloud, transformation services will be retired and no replacement services in the cloud are planned for GLAS/ICESat L1B Global Elevation Data (HDF5), Version 34 (GLAH06). As a result, downloading a subsetted GLAH06 file in HDF5 format is no longer an option within the OpenAltimetry web application.
Downloading CSV files containing the elevation data continues to be an option in OpenAltimetry. These CSV files include the name of the corresponding GLAH06 file, so that users may access the full HDF5 files using another method, e.g. NASA Earthdata Search. These changes do not apply to the ATLAS/ICESat-2 side of the web application. Please visit this webpage for guidance on using OpenAltimetry to access GLAS/ICESat data:
