PyGEM_RT — Frontal Ablation Calibration Branch

This branch contains the PyGEM modifications used for the frontal ablation calibration study:

"Joint Bayesian Calibration of Frontal Ablation and Surface Mass Balance in Global Glacier Models" (GMD Preprint, 2026)

Key modifications:

• Added monthly mass balance functions and new parameters to get_annual_mb
• Added volume_m3_annual/month_ice outputs and glac_wide_massbalclim variable in the mass balance class
• Integrated length change as an extra glacier variable for terminus tracking
• Refactored calving flowline functions with cleaner workflow logic
• Custom output handlers to export frontal ablation flux alongside standard mass balance outputs
