In the last years climate change exacerbation intensified glaciers’ retreat. The importance of knowing and monitoring the local processes of melting and accumulation of snow and ice is paramount to evaluate the consequences of this phenomena on water resources and ecosystems. Improved knowledge of meteorological conditions allows a better prediction of snow/ice dynamics and of glacial bodies reduction. The objective of this thesis is to explore and compare available solutions for the meteorological monitoring in alpine environment, in relation to the monitoring of temperature and precipitations which determine the glacial retreat. The thesis is therefore divided in two parts. The first part consists in the assessment of a radar rain gauge for precipitation measurements in high mountain environments, and the comparison with a weighing rain gauge and official data collected in situ.
