IceBridge Narrow Swath ATM L1B Elevation and Return Strength, Version 2

This data set contains spot elevation measurements of Greenland, Arctic, and Antarctic sea ice acquired using the NASA Airborne Topographic Mapper (ATM) narrow-swath instrumentation. The data were collected as part of Operation IceBridge funded aircraft survey campaigns.

This is the most recent version of these data.

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.

  • Beginning with the 2013 Greenland campaign, the data file format is HDF5.
  • Qfit data files for all previous campaigns are to be replaced with HDF5 files.
  • The data set title (longname) changes from "IceBridge Narrow Swath ATM L1B Qfit Elevation and Return Strength" to "IceBridge Narrow Swath ATM L1B Elevation and Return Strength".
