Input data for Elbrus Western Plateau (Caucasus) ice flow model

A three-dimensional steady state full Stokes flow model for a cold glacier with a rheological law accounting for firn densification was applied both in a purely mechanical and in a thermomechanically coupled versions. Using this model, the ice velocity field was simulated in the central part of the the Western Plateau (WP) of Elbrus. To model the flow and determine the age of ice/firn in the WP glacier, we used the following data: 1. Glacier surface and bedrock with a cell size of 10×10 m, obtained in 2017 based on radar surveys. 2. Temperature distribution in a deep-drilling borehole obtained from measurements in 2009. 3. Ice/firn density distribution in the 2009 deep ice core. 4. Ice/firn age distribution in the 2009 ice core with a resolution of about one year, obtained by laboratory methods (upper 168.6 m).
