OGGM is a modelling framework able to simulate past and future mass balance, volume, and geometry of glaciers and it can account for glacier geometry (including contributory branches) and features several glacier evolution models, including an explicit ice dynamics module. The modeling chain comprises data downloading tools (glacier outlines, topography, climate, validation data), a preprocessing module, a mass-balance model, a distributed ice thickness estimation model, and an ice-flow model. The monthly mass balance is obtained from gridded climate data and a temperature index melt model. OGGM explicitly simulates glacier dynamics: the model relies on the shallow-ice approximation to compute the depth-integrated flux of ice along multiple connected flow lines.
