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) 4CT3 narrow scan instrumentation. The data were collected as part of Operation IceBridge funded aircraft survey campaigns.

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".
