Abstract

This research aims to exploit the potentialities of multi-mission SAR data at X-, C- and L-band for the monitoring of snowpack and alpine soils. The snow parameters as snow water equivalent, snow liquid water content and snow metamorphism have been monitored and different methods are proposed for their retrieval. In order to gather consistent datasets, experimental activities have been conducted in two selected sites in Northern Italy, which are covered by alpine snow during winter and spring periods and are in some cases characterized by the presence of permafrost. Microwave responses of snow and soil have been then simulated by using electromagnetic (i.e., AIEM, Oh, SFT and DMRT-QCA), and physical models (SNOWPACK). Finally, machine learning approaches, as Artificial Neural Networks and Random Forest, were implemented for retrieving snow parameters; whereas interferometric techniques were used in case of snow and soil displacement as rock glaciers. Preliminary and consistent results have been obtained in terms of estimate of snow parameters and soil displacement. This multi-frequency/multi-mission approach enhances the ability of SAR sensors to monitor and analyze snow dynamics, contributing to improved decision-making in various domains.

Abstract

Seasonal Alpine snowpack is an important reservoir of fresh water useful for human and agricultural purposes and for hydroelectric power generation. Thus, monitoring the evolution of the snow is very useful to control this important factor. To do this, different approaches are used. Among them, microwave-based devices are used, but show some limitations due to the impossibility to retrieve the parameters without a priori assumptions or complementary information about the snowpack, or complex data processing. This paper present a portable radar architecture able to overcome this limitation by using a dual-receiver system. The device was already tested for the S-band. Now, a multi-spectral analysis is tested for the first time to retrieve values of depth, density and snow water equivalent (SWE), for dry snow. The system was tested in real field sites in the Italian Alps during late winter 2022. The overall results were in good agreement with manual measurements.
