Currently, glaciers (here defined as all glaciers other than the ice sheets) contribute approximately just as much to global sea level as the Antarctic and Greenland ice sheets combined, and will continue to be important contributors during the 21st century. They are also important regulators of seasonal water availability in many regions, and both growing and shrinking glaciers may cause geohazards. Hence, it is essential to develop accurate predictive tools of the glaciers’ response to climate variability and change suitable for regional to global scales.
The overall goal is to provide – for the first time - a framework for a coordinated intercomparison of global-scale glacier mass change models to foster model improvements and reduce uncertainties in global glacier projections.
The specific objectives are:
Our goals will be achieved through a community-based definition of standardized experiment designs, forcing data, and deliverable output variables, as well as the definition of deadlines, milestones and deliverables.
The 4-year activity was started in February 2015. Modelers performing global-scale modeling are invited to participate in the model intercomparison. Participants are expected to:
Modeling efforts including at least one entire major RGI region (e.g. all glaciers in the High Asian Mountains) are also welcome.
