Swiss Glacier Mass Balance (release 2025)

Direct measurements of glacier mass balance - the sum of snow accumulation and snow/ice melt - are carried out on selected glaciers in Switzerland. Based on point observations, typically acquired in April/May and September, glacier-wide quantities of seasonal mass balance (winter/summer/annual) are evaluated, expressed as a an area-averaged value of water eqivalent. The dataset contains all available observations up to present and is delivered as four separate .csv files with results both for the exact measurement periods (observation, varying between the years) and the hydrological year (fixdate), as well as for glacier-wide quantities and for individual elevation bins.
