IceBridge Narrow Swath ATM L1B Elevation and Return Strength with Waveforms, Version 1

This data set contains spot elevation measurements with corresponding waveforms of Greenland, Arctic, and Antarctic sea ice. The data complement the IceBridge ATM L1B Near-Infrared Waveforms data, which are measured at near-infrared wavelength. Both of these narrow-swath data sets are closely related to the wide-swath IceBridge ATM L1B Elevation and Return Strength with Waveforms data set. The data were acquired as part of aircraft survey campaigns funded by Operation IceBridge.

This is the most recent version of these data.
