OGGM is a modular open source model for glacier dynamics

OGGM is able to simulate past and
future mass balance, volume and geometry of (almost) any glacier in the world,
in a fully automated and extensible workflow.

The model accounts for glacier geometry (including contributory branches) and
includes an explicit ice dynamics module. We rely exclusively on publicly
available data for calibration and validation. OGGM is modular and
supports novel modelling workflows
: it LOVES to be remixed and reused!
