Incorporated models or components:

Spatial dimensions	2D
Spatial extent	Reach-Scale, Patch-Scale
Model domain	Hydrology, Cryosphere
One-line model description	openAMUNDSEN is a modular snow and hydroclimatological modeling framework written in Python.
Extended model description	openAMUNDSEN is a fully distributed model, designed primarily for resolving the mass and energy balance of snow and ice covered surfaces in mountain regions. Typically, it is applied in areas ranging from the point scale to the regional scale (i.e., up to some hundreds to thousands of square kilometers), using a spatial resolution of 10–100 m and a temporal resolution of 1–3 h, however its potential applications are very versatile.
