Glacier length changes are measured annually at the tongues of all larger and on many of the smaller Swiss glaciers and provide an overview of their long-term variations. The dataset contains all available observations up to present and is delivered as a .csv file.

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 equivalent (w.e.). 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 (fix-date), as well as for glacier-wide quantities and for individual elevation bins.

The comparison of digital elevation models derived from aerial remote sensing allows the computation of glacier ice volume changes over periods of years to decades. Ice volume changes have been converted to geodetic mass balances assuming a density of volume change of 850 kg/m³. The dataset contains all available observations for the most important Swiss glaciers up to present and is delivered as a .csv file.

Length Change Classification

Temporal pattern of length change for every glacier with ongoing measurements classified according to advance (blue), stationary station (green) and retreat (red). Glaciers are displayed in descending order of current glacier length. : link to Figure

Length Change Variation

Fraction of classified annual glacier length change (advancing, stationary and retreating) for all glaciers with long-term measurement series (annual number of observations shown in top panel). The bottom panel shows the cumulative length change of four iconic glaciers with different characteristics throughout Switzerland. : link to Figure

Course of Massbalance

Modelled cumulative course of daily glacier-wide mass balance in the current year constrained by seasonal in situ surveys (black triangles). The average variation of cumulative daily mass balance in the previous 10 years is shown with the grey shading and the top bar provides a classification of the state of the current year relative to the 10-year average. : link to Figures

Massbalance Anomaly Annual

Anomaly of individual observations of glacier-wide ANNUAL mass balance (solid dots) relative to the glacier-specific average of the previous 10 years. Numbers for the individual measurements are given referring to the hydrological year (1 Oct to 30 Sept). Small dots show a regional extrapolation to indicate spatial trends. Years since 2000 are shown in reversed order. : link to Figures

Massbalance Anomaly Winter

Anomaly of individual observations of glacier-wide WINTER accumulation (solid dots) relative to the glacier-specific average of the previous 10 years. Numbers for the individual measurements are given referring to a fixed period (1 Oct to 30 April). Small dots show a regional extrapolation to indicate spatial trends. Years since 2000 are shown in reversed order. : link to Figures

Massbalance Anomaly Summer

Anomaly of individual observations of glacier-wide SUMMER mass loss (solid dots) relative to the glacier-specific average of the previous 10 years. Numbers for the individual measurements are given referring to a fixed period (1 May to 30 Sept). Small dots show a regional extrapolation to indicate spatial trends. Years since 2000 are shown in reversed order. : link to Figures

Volume Evolution

Evolution of total glacier ice volume since 1980 based on today’s total measured ice volume and a spatial extrapolation of observed mass balance. Results are both shown for all Swiss glaciers, and specified for individual hydrological basins. Numbers for relative ice volume changes are both given for decadal time periods (light blue), and at the annual scale. : link to Figures

Relative Ice Volume Change

Relative annual change in total Swiss glacier ice volume with respect to the previous year. Colours indicate extreme loss (red), strong loss (orange), moderate loss (grey), and gain (blue). The blue shading in the background shows the evolution of overall Swiss glacier volume since 2000. : link to Figure
