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.本数据集仓库收录了瑞士拉萨永山谷（Vallée de la Sionne）试验场发生的一起自然大型粉雪雪崩（powder snow avalanche，编号20213009）现场采集的次声波（infrasound）、GEODAR雷达（GEODAR radar）与多普勒雷达（Doppler radar）数据。 本数据集可作为下述已投稿文献的补充数据，并在该文献中得到详细阐述： B. Sovilla、E. Marchetti、M. Kyburz、A. Köhler、P. Huguenin、I. Calic、M.J. Kohler、E. Surinach与C. Pérez-Guillén，《粉雪雪崩次声波产生的主要源机制》，已提交至《Geophysical Research Letters（地球物理研究快报）》，目前处于审稿阶段。
