2. SUMMARY DATA
Specific net balance (b), equilibrium line altitude (ELA) and accumulation area ratio (AAR) of all glaciers from the balance years 1993/94 and 1994/95 are presented in Part 2.1. The AAR values are given as integer values only.
Values for ELA0 and AAR0 are given in addition. They represent the calculated ELA and AAR values for a zero net balance, i.e., a hypothetical steady state. All values since the beginning of mass balance measurements were used for this calculation on each glacier. Minimum sample size for regression was defined as 6 ELA or AAR values. Some of the observed glaciers can entirely become ablation or accumulation areas in extreme years. Corresponding AAR values of 0 or 100%, as well as ELA values outside the altitude range of the observed glaciers were excluded in the calculation of AAR0 and ELA0 values. The corresponding graphs (AAR and ELA, respectively, versus specific net balance) are given in Chapter 3, but only for the glaciers with extensive information.
The graphs in the second part of this Chapter (2.2) present the development of cumulative specific net balance over the whole observation period for each glacier where two or more net balances were calculated.
It is planned to make available in the first issue of a new publication series "World Glacier Monitoring - Updates and Assessments" the complete data set used to calculate the ELA0/AAR0 values and which forms the basis of the cumulative specific net balance graphs.
