Development and deployment of innovative sensors for contact and non-contact measurement of the snow profile Phase 5 - Data analysis during operational test season

This project includes the data evaluation of the first operational data from sensors developed in previous projects using UAV/UAS for the contactless and non-contact recording of snow data. This method enables interference-free measurement of temperature, humidity, pressure and movement on avalanche slopes. The sensors are deployed in a test field in open terrain using UAV/UAS. A sensor network consisting of several sensor measurement boxes is set up at specific test locations. Regular data acquisition is carried out via a mobile base station which is stationary or mobile on the UAV. Furthermore, a concept is being developed on how avalanche commissions can use the data to assess local avalanche slopes. In previous projects, we have already developed a measuring system for moisture and temperature measurements in inaccessible avalanche starting areas, particularly with regard to sliding snow avalanches. With the measuring system developed in the preliminary projects, we are starting the first operational season this year on real avalanche slopes relevant to ÖBB. The measurement results will be checked for their practical suitability, validated with reference measurements, the data scientifically analysed and a final report written. We are aiming for an SCI publication as a scientific publication.
