(a) Arithmetic mean of glacier mass-balance measurements, calculated annually sincethe beginning of measurements, together with the number of these glaciers. Mean mass balancescalculated for all glaciers are also presented in Appendices 1 and 3. (b) Glacier mass-balance calculatedfor glaciers with mass-balance records 20 years and longer, and square-root error. (c) Glacier massbalances calculated for glaciers with mass-balance records 30 years and longer, and square-root error.(d) Extreme mass-balance values for glaciers with mass-balance records 20 years and longer. (e)Cumulative mass-balance sums given for all measurements, and for those with records 20 years andlonger.50
