Vallée de la Sionne Snow Avalanche n. 20213009: GEODAR radar, Doppler radar and infrasound data

This repository hosts infrasound, GEODAR radar, and Doppler radar data collected within a large powder snow avalanche (No. 20213009) that occurred naturally at the Vallée de la Sionne test site in Switzerland. These datasets complement and are described in the following publication: B. Sovilla, E. Marchetti, M. Kyburz, A. Köhler, P. Huguenin, I. Calic, M.J. Kohler, E. Surinach, and C. Pérez-Guillén, under review. "The dominant source mechanism of infrasound generation in powder snow avalanches," submitted to Geophysical Research Letters.
