GEODAR data of snow avalanches at Vallée de la Sionne: Seasons 2010/11, 2011/12, 2012/13 & 2014/15 [Data set]

This data repository contains radar data from 77 snow avalanches recorded using the GEODAR (GEOphysical flow dynamics using pulsed Doppler radAR) system at the Swiss full-scale avalanche testsite Vallée de la Sionne. GEODAR is a purpose built, advanced phased-array FMCW system.

The data contain range-time plots of intensities gained from moving target identification (MTI) processing (-MTI.h5), an PDF preview image (-MTI.pdf), the trajectory of the front in range and time (-TRAJ-001.h5), the corresponding Thalweg as steepest descent from release area (-Thal-001.h5) and a processing info file in Matlab format (-info.mat).

This document covers details about the different versions of the radar setup and raw data processing steps as well as a description of the repository content (see file geodar_repository.pdf).
