This is the most recent version of these data.
Version Summary
Version Summary
Version 2 data are in HDF5 format beginning with the 2013 Arctic campaign.
Version 1 data are in Qfit binary format for 2012 and earlier campaigns.
Version 1 data are in Qfit binary format for 2012 and earlier campaigns.
- Qfit data files for all previous campaigns were replaced with HDF5 files.
- The Version 2 data set title changed from "IceBridge ATM L1B Qfit Elevation and Return Strength" to "IceBridge ATM L1B Elevation and Return Strength".
Overview
This data set contains spot elevation measurements of Arctic and Antarctic sea ice, and Greenland, Antarctic Peninsula, and West Antarctic region ice surface acquired using the NASA Airborne Topographic Mapper (ATM) instrumentation. The data were collected as part of Operation IceBridge funded aircraft survey campaigns.

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.Users have the option to
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).
