Le variazioni di lunghezza dei ghiacciai sono misurate annualmente in corrispondenza del fronte di tutti i maggiori ghiacciai svizzeri così come per numerosi ghiacciai di dimensioni più ridotte. Queste misure forniscono informazioni sulle variazioni di lungo termine dei ghiacciai svizzeri. La serie dati comprende tutte le osservazioni disponibili fino al presente ed è fornita in formato .csv.

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
Misure dirette del bilancio di massa - la somma di accumulo nevoso e ablazione - vengono condotte su un gruppo selezionato di ghiacciai svizzeri. Il bilancio di massa stagionale (invernale/estivo) ed annuale viene calcolato sulla base di osservazioni puntuali, tipicamente condotte in aprile/maggio e settembre, ed espresso come un valore di acqua equivalente (w.e.) distribuito omogeneamente sull'estensione del ghiacciaio.
La serie dati comprende tutte le osservazioni disponibili fino al presente ed è fornita in formato .csv. Sono inclusi i risultati distribuiti sulla superficie del ghiacciaio e divisi per classi di altitudine.

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
Il confronto tra modelli digitali del terreno ottenuti con tecniche di telerilevamento permette il calcolo delle variazioni di volume dei ghiacciai per periodi temporali che variano da pochi anni fino a diverse decadi.
Le variazioni di volume vengono convertite in bilanci di massa geodetici assumendo una densità volumetrica del ghiaccio di 850 kg/m³. La serie dati contiene tutte le osservazioni disponibili per tutti i più importanti ghiacciai svizzeri fino al presente ed è fornita in formato .csv.
Variazioni del volume dei ghiacciai
Variazioni del volume, variazioni medie dello spessore, bilanci di massa annuale (metodo geodetico). DOWNLOAD

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
