The multi-offset ground-penetrating radar (GPR) data can be used to estimate the snow and firn depth and density along the traversed route. When combined with information about the age of the firn, the radar-derived depth and density can be used to estimate the surface mass balance. These data are pre-processed, meaning, the radar waveforms are unprocessed, but have been quality controlled and georeferenced. The netcdf data files contain the georeferenced trace header and the unprocessed and multiplexed GPR traces.
