An open source glacier model in Python
About
OGGM is an open source modelling framework for glaciers
The model can simulate past and future mass-balance, volume and geometry of (almost) any glacier in the world in a fully automated and extensible workflow. OGGM is modular and supports novel modelling workflows: it loves to be remixed and reused! OGGM also brings together a vibrant and friendly community of scientists, modellers and educators.
Please get in touch with us if you are interested in using the model or if you’d like to contribute to the project!
These videos were created with oggm-3dviz based on an OGGM simulation. Check out our tutorials to create your own!
Mission
Global not only in the sense of leading to meaningful results for all glaciers combined, but also for any small ensemble of glaciers, e.g. at the headwater catchment scale. Modular to allow different approaches to the representation of ice flow and surface mass balance to be combined and compared against each other. Open source so that the code can be read and used by anyone and so that new modules can be added and discussed by the community, following the principles of transparency and open governance. Consistent in order to provide well-defined uncertainty measures at all realizable scales.
Motivation
Our project is motivated by the far reaching goal of contributing (and helping others to contribute) to answers of some of the “big questions” in Earth Sciences:
- How much ice is stored on the glaciers on Earth?
- How much ice was present on Earth at the beginning of the 20th century, and how much ice will be lost by the end of the 21st?
- How will this affect water resources, and how to help communities to prepare for these changes?
- What are the uncertainties associated with these numbers, and where do they originate?
- How much model complexity is just right?
- and more.
