- •
The VOLTA model is presented to estimate ice thickness distribution and volume.
- •
The model requires just glaciers outlines and a DEM as inputs.
- •
VOLTA can rapidly estimate volume and bed topography for multiple glaciers.
- •
The model was tested against glaciers with independent field based observations.
- •
Modelled volumes were between 26.5% (underestimate) and 16.6% (overestimate).
