ICESat-2: MATLAS Documentation

Caution on usage of MATLAS Data Release 2

MATLAS data simulates the expected performance of the ICESat-2 ATLAS instrument. It is produced from MABEL granules by adjusting that data\'s detected number of signal and noise photons to that predicted using ATLAS instrument model design cases. The MATLAS data uses an HDF5 format similar to the MABEL data Release 10. This work is preliminary and the quality of the simulation products has not been fully evaluated.

Please verify you are working with the latest release of the data by referring to the ICESat-2 MATLAS data distribution site. Refer to the release notes and standard data product descriptions for information on changes in data attributes and/or processing methods in future releases.

As stated this is a preliminary release and additional calibrations and improvements may be done. Please email Kaitlin Walsh ( with a copy to Tom Neumann ( and David Hancock ( regarding any quality issues you identify while working with the data or if you have questions about these data. This will be helpful to us as we continue to improve the MATLAS data products.
