data, a remote sensing analysis was carried out on walls facing, respectively, North and South, with measures of temperature, light polarization and spectral response in the visible and in the near infrared bands. First results are promising and for the future we wish to develop a simple system, usable by non-specialist, to acquire information on the state of aggregation of snow, also on vertical profiles made accessible by trenches, as normally used in the classical nivological survey. Acknowledgements. The authors wish to thank the whole team that conducted these test sessions on the Presena Glacier: the Hydrology group of the Professor A. Bellin, Department of Civil, Environmental and Mechanical Engineering Trento University; A. Trenti, Director of the Forecasting and Planning Office, Provincia of Trento, with the technical working group of Meteotrentino. And, for the support, the Consorzio Adamello Sky that manages the ski lifts facilities on the Presena Glacier.
