Glacier melt conditions (i.e., null surface temperature and positive energybudget) can be assessed by analyzing data acquired by a supraglacialautomatic weather station (AWS), such as the station installed on thesurface of Forni Glacier (Italian Alps). When an AWS is not present, theassessment of actual melt conditions and the evaluation of the melt amountis more difficult and simple methods based on T-index (or degree days)models are generally applied. These models require the choice of a correcttemperature threshold. In fact, melt does not necessarily occur at daily airtemperatures higher than 0 °C. In this paper, we applied bothenergy budget and T-index approaches with the aim of solving this issue. We start by distinguishing between the occurrence of snowmelt and thereduction in snow depth due to actual ablation (from snow depth datarecorded by a sonic ranger). Then we find the daily average temperaturethresholds (by analyzing temperature data acquired by an AWS on ForniGlacier) which, on the one hand, best capture the occurrence of significantsnowmelt conditions and, on the other, make it possible, using the T-index,to quantify the actual snow ablation amount. Finally we investigated theapplicability of the mean tropospheric lapse rate to reproduce airtemperature conditions at the glacier surface starting from data acquired byweather stations located outside the glacier area. We found that the mean tropospheric lapse rate allows for a good and reliablereconstruction of glacier air temperatures and that the choice of anappropriate temperature threshold in T-index models is a very importantissue. From our study, the application of the +0.5 °Ctemperature threshold allows for a consistent quantification of snow ablationwhile, instead, for detecting the beginning of the snow melting processesa suitable threshold has proven to be at least −4.6 °C
