Release Schedules

The table below summarizes the release schedule of NASA ICESat/GLAS data. The table is ordered by laser campaign, with the most recently received campaign listed first. We recommend you work with the latest release of data which is the highest release number and includes improvements to product algorithms. For information on past releases of ICESat/GLAS data, see the Past Release Schedule Web page.

The latest altimetry products are Release 34, and the latest atmospheric products are Release 33.

The ICESat GLAS HDF5 data were converted directly from the original binary data. Data files were not re-processed during conversion. However, parameters in the HDF5 files are re-ordered, re-named, and logically grouped to take advantage of the HDF5 file structure.  Binary data files were removed on 01 August 2017, fully replaced by HDF5 files.
