# A modular open source glacier model in Python¶

The model accounts for glacier geometry (including contributory branches) and includes an explicit ice dynamics module. It can simulate past and future mass-balance, volume and geometry of (almost) any glacier in the world in a fully automated and extensible workflow. We rely exclusively on publicly available data for calibration and validation.

This is the model documentation for users and developers of the latest (cutting-edge) repository version. For the documentation of the latest stable release, visit docs.oggm.org/en/stable.
