Climate variations in a high altitude Alpine basin and their effects on a glacial environment (Italian Western Alps)
The main objective of this study is to evaluate the variations of climatic parameters (temperature, rain and snow) measured by two weather stations (Formazza and Sabbione) that have never been analyzed before, located in a high glacial catchment (the Sabbione basin in the Italian Western Alps). The...
