The primary data product from the ATM laser altimeter is “QFIT”.  A QFIT file is a collection of geolocated laser shots tagged with time and elevation.  ICESSN is a sub-sampled version of QFIT which separates the data in platelets making it smaller and easier to analyze.  An example of QFIT vs ICESSN is in the image below
