The model builds upon Marzeion et al., (2012) and intends to become a global scale, modular, and open source model for glacier dynamics. The model accounts for glacier geometry (including contributory branches) and includes a simple (yet explicit) ice dynamics module. It can simulate past and future mass-balance, volume and geometry of any glacier in a fully automated workflow. We rely exclusively on publicly available data for calibration and validation.
The project is currently in intense development. Get in touch with us if you want to contribute.
We use the Hintereisferner as benchmark:
We first define a local grid and compute the centerlines (Kienholz et al., 2014) as well as the downstream flowlines:
The glacier is then represented as several flowlines of varying width:
Finally, following an inversion algorithm based on mass-balance (Marzeion et al., 2012) and ice-flow dynamics (Farinotti et al., 2009), we derive the ice thickness of the glacier:
