Winter campaign in Davos is concluded!

22.04.2016

An innovative campaign for the measurement of polarimetric and interferometric response of snow at Ku-band has been performed in Davos, from January to April 2016.

Under a collaboration between ETH Zürich and SLF Davos, a measurement campaign has been conducted in Davos using our Ku-band Advanced Polarimetric Radar Interferometer (KAPRI). We were able to acquire an innovative dataset that will allow us to analyse the evolution of snow properties over the winter. KAPRI was deployed in its radome in December 2015 at our field site in Davos. Every 4 minutes, 8 images (in HH, VV, VH and HV polarisation with 2 sets of receiver antennas) of the south-east facing Dorfberg slope were acquired and thus we were able to observe snowfall, rain, snowmelt, storm and avalanches over the course of the winter. 10 minute interval time-lapse photography as well as UAV measurements for snow height were performed for reference of the data. In total, we acquired around 40 TB of data. In the next phase, we shall be processing, analysing and interpreting the final results.
