Swiss Glacier Point Mass Balance Observations (release 2022)

Direct observations of point glacier mass balance have been carried out at one up to several dozens of sites on more than 50 individual glaciers in the Swiss Alps over the past century. The measurements represent the basis for seasonal mass balance monitoring. Data are aggregated to three time periods - annual (referring to a time interval of about 1 year, e.g. Oct.-Sept.), winter (referring to an entire winter season, e.g. Oct.-May), or intermediate (referring to an arbitrary period of a day up to several months). Metadata and estimated uncertainties are specified for different variables according to a system of quality indicators.
