The Supplementary Material provides detailed results for each glacier in subfolders: 
1. Abramov
2. Glacier No. 354
3. Golubin

The following types of results are provided:
- model_evaluation.txt: Evaluation of calibration procedure for each year. The table shows the final, calibrated value for the Degree Day Factor for snow (DDFsnow) and for the Precipitation Correction Factor (Cprec), as well as the resulting annual surface mass balance (SMB) for each year. The Root Mean Square Error between the modelled melt and modelled winter snow accumulation (RMSEswe)  and the Root Mean Square Error between observed and simulated Snow Covered Area Fraction (RMSEscaf) is given as a measure of model calibration performance. 
- model_results_daily_*year*.txt: Modelled cumulative daily surface mass balances (SMB), snow covered area fractions (SCAF) and transient snowline (TSL) for all investigated years
- SCAF_observed.txt: Observed snow-covered area fraction for each transient snowline observation date
